Skip setting focused window to the recents animation target

- If there's a recents animation running, the target controls whether
  to finish to home (and resume the task), and with live tile,
  Launcher expects to stay started (but not resumed) until it finishes
  the transition.

Fixes: 185317835
Test: Open an app that supports overview sharing and repeatedly enter
      Overview and trigger sharing
