Finish LauncherLayoutListener when launcher transition animation ends.

In QuickScrub mode, the right task gets clipped out at the end of the animation. This is because LauncherLayoutListener continues to clear out where CurrentRect is, while the app surface is not displaying. We want to finish the listener after the transition animation.
