Fallback recents should wait for remote anim ready

Hook into the remote animation API on the recents view for the
fallback recents code path. This ensures the views are attached before
attempting the layout animation.

Bug: 132112131
Test: Set separate default launcher, go to recents from app, views
animate correctly
