[ReactNative] Fix case where scenes are not reset on gesture detaching

Browse Source 
Summary:
Sometimes, when quicly backing out of a gesture, the scene isn't fully reset to the middle position and remains offset by a few pixels. This makes sure that never happens.

@public

Test Plan: Tested on iOS and I can no longer see the scenes stop when backing out of a gesture
