Reset the force-invisible flag after the animation into launcher completes.

- In the case where an app auto-enters into PiP, we don't run the
  predefined remote animation, which means that the force-invisible flag
  is never reset. With ag/3876550, we can rely on enter animation complete
  to be called after the transition, and we can reset the flag here as well.
