Timeline: Added describe-sections to PointItem unit tests

[wimrijnders]

Small fix on the unit tests for better output layout. Before the fix:

 Timeline PointItem
    ✓ should initialize with minimal data
    ✓ should have a default width of 0
    ✓ should error if there is missing data
    ✓ should be visible if the range is during
    ✓ should not be visible if the range is after
    ✓ should not be visible if the range is before
    ✓ should be visible for a "now" point with a default range
    ✓ should redraw() and then not be dirty
    ✓ should redraw() and then have point attached to its parent
    ✓ should redraw() and then have the correct classname for a non-editable item
    ✓ should redraw() and then have the correct classname for an editable item (with object option)
    ✓ should redraw() and then have the correct classname for an editable item (with boolean option)
    ✓ should redraw() and then have the correct classname for an editable:false override item (with boolean option)
    ✓ should redraw() and then have the correct classname for an editable:true override item (with boolean option)
    ✓ should redraw() and then have the correct classname for an editable:false override item (with object option)
    ✓ should redraw() and then have the correct classname for an editable:false override item (with object option for group change)
    ✓ should redraw() and then have the correct classname for an editable:true override item (with object option)
    ✓ should redraw() and then have the correct classname for an editable:true non-override item (with object option)
    ✓ should redraw() and then have the correct classname for an editable:false non-override item (with object option)
    ✓ should redraw() and then have the correct property for an editable: {updateTime} override item (with boolean option)
    ✓ should redraw() and then have the correct property for an editable: {updateTime} override item (with boolean option false)
    ✓ should redraw() and then have the correct property for an editable: {updateGroup} override item (with boolean option)
    ✓ should redraw() and then have the correct property for an editable: {updateGroup} override item (with boolean option false)
    ✓ should redraw() and then have the correct property for an editable: {remove} override item (with boolean option)
    ✓ should redraw() and then have the correct property for an editable: {remove} override item (with boolean option false)
    ✓ should redraw() and then have the correct property for an editable: {updateTime, remove} override item (with boolean option)
    ✓ should redraw() and then have the correct property for an editable: {updateTime, remove} override item (with boolean option false)
    ✓ should redraw() and then have the correct property for an editable: {updateTime, updateGroup, remove} override item (with boolean option)
    ✓ should redraw() and then have the correct property for an editable: {updateTime, updateGroup, remove} override item (with boolean option false)

With this fix:

Timeline PointItem
    ✓ should initialize with minimal data
    ✓ should have a default width of 0
    ✓ should error if there is missing data
    ✓ should be visible if the range is during
    ✓ should not be visible if the range is after
    ✓ should not be visible if the range is before
    ✓ should be visible for a "now" point with a default range
    should redraw() and then
      ✓ not be dirty
      ✓ have point attached to its parent
      have the correct classname for
        ✓ a non-editable item
        ✓ an editable item (with object option)
        ✓ an editable item (with boolean option)
        ✓ an editable:false override item (with boolean option)
        ✓ an editable:true override item (with boolean option)
        ✓ an editable:false override item (with object option)
        ✓ an editable:false override item (with object option for group change)
        ✓ an editable:true override item (with object option)
        ✓ an editable:true non-override item (with object option)
        ✓ an editable:false non-override item (with object option)
        ✓ an editable: {updateTime} override item (with boolean option)
        ✓ an editable: {updateTime} override item (with boolean option false)
        ✓ an editable: {updateGroup} override item (with boolean option)
      have the correct property for
        ✓ an editable: {updateGroup} override item (with boolean option false)
        ✓ an editable: {remove} override item (with boolean option)
        ✓ an editable: {remove} override item (with boolean option false)
        ✓ an editable: {updateTime, remove} override item (with boolean option)
        ✓ an editable: {updateTime, remove} override item (with boolean option false)
        ✓ an editable: {updateTime, updateGroup, remove} override item (with boolean option)
        ✓ an editable: {updateTime, updateGroup, remove} override item (with boolean option false)
