ngAnimate: Cannot re-enable animations with `$animate.enabled`

[dcherman]

If you are a descendant of an element that potentially called $animate.enabled(elem, false), you cannot re-enable animations on yourself by calling $animate.enabled(elem, true)

It looks like when you do the latter, the element is simply removed from the internal HashMap rather than having a value toggled. As a result, the while loop that checks whether or not animations are enabled for a given element only considers whether or not a parent is disabled, not whether or not it's explicitly enabled.

Looks like a bug to me, but let's ask @matsko if this is intended behavior.
