Fix weird task launch animation

Sometimes a weird task launch animation can be observed where the task is animated to fullscreen before animated again from center to the left side of the screen. This is caused by stateManager.moveToRestState() call that internally animates FULLSCREEN_PROGRESS to 0 based on its launcher state (normal). The implementation right now finishes the recents animation after this call, instead of before. We should finish the recents animation first before doing the recents view clean up work.
