Update-GSCalendarEvent sets default Start/End times if not passed

[scrthq]

Working with @Rtistx on this, should be a quick fix.

Issue is that if you do not specify a Start and/or End time when updating a Calendar event with Update-GSCalendarEvent, it will set the start time as the time the command was run and the end time 30 minutes after that point due to the parameters LocalStartTime and LocalEndTime having the same default values as New-GSCalendarEvent

Code that needs updating is here:

https://github.com/scrthq/PSGSuite/blob/master/PSGSuite/Public/Calendar/Update-GSCalendarEvent.ps1#L104..L107 (needs to have the default values removed)

https://github.com/scrthq/PSGSuite/blob/master/PSGSuite/Public/Calendar/Update-GSCalendarEvent.ps1#L183 (needs to be changed to an elseif statement)

https://github.com/scrthq/PSGSuite/blob/master/PSGSuite/Public/Calendar/Update-GSCalendarEvent.ps1#L198 (needs to be changed to an elseif statement)
