Fix seeing "punch-hole" split-tasks when switching tasks from recents

If split-screen task is on the overview, since it has controlled by
recents remote animation, we should not dismiss split-screen, in case
when taping the side task on the overview to perform launch fullscreen
task transition and animating split-screen in parallel but the
transition leash can't control the split-tasks because of the
split-screen dismissal.

Fix: 228965939
Test: manual as issue steps:
  1) launch several fullscreen apps
  2) enter split-screen mode from the overview
  3) swipe the split-screen task to overview again
  4) tap the side task to let it going to foreground
  5) verify the split-screen task should keep visible and
     animating as well.
