FLEX-33163 - if a List's dataProvider receives a "reset" collection event, even if the selectedIndex doesn't change, the selectedItem does, so a "valueCommit" event must be dispatched to trigger bindings on selectedItem. 

Add new List_events_collectionKind_reset_bug test.

QE: Passed mustella tests for spark List, Spinner, ButtonBar, and TabBar.
