Invalidate entire scene root when executing the transition.

Bug 27778109

When switching from forced visibility to using real visibility,
I didn't take into account the fact that invalidating INVISIBLE
Views skip invalidation. This CL invalidates the scene root
to ensure that the transition is properly executed.
