grabHelper: Fix ungrabbing properly

Browse Source 
Make sure to account for modalCount properly, rather than just
tracking modalCount for the last actor on the stack. Additionally,
traverse the popped actors in the reverse order so that onUngrabbed
callbacks are called at the proper place in time.
