The recents animation can sometimes start before launcher has started when started with 3-button mode. This causes the animation to start before the recents UI has been initialized by Launcher. Added a callback to properly synchronize launcher start and the recents animation.
Fixes: 229360539
Test: started the recents animation and checked logs (order of operations), when the recents animation or launcher started first
