[Bugfix][RemoteAnimation] Fix IndexOutOfBoundsException in onAnimationFinished of

RemoteAnimationController

Sometimes mPendingAnimations.remove will be called more than once in one cycle (line 255 - 270) of 
onAnimationFinished, e.g., mPendingAnimations.remove being called again in 
adapters.mAdapter.mCapturedFinishCallback.onAnimationFinished, resulting in 
IndexOutOfBoundsException.
