Fix splitting with wrong apps when entering split with rotation

Browse Source 
Use mSplitRequest to determine if it's entering split instead, rename
the flag to mIsDividerRemoteAnimating which is more accurate to what it
stands for. When reseting divider remote animating flag, it should not
affect other logic for entering split screen besides divider visibility.
