Reviewed by Eric Carlson.

When a page requests element fullscreen when the video inside the target is in PiP,
the state machine gets confused, thinking the app is existing auto-pip. This area
of code is deeply in need of a re-factoring, but until then, explicity return the
video layer to its original WebAVPlayerLayer at the end of didStopPictureInPicture().
