Handle long press directly if recents transition is deferred

- For 3p launchers, the starting of the home activity is deferred until
  the user moves past a slop, in these cases we don't need to worry
  about finishing the recents transition before handling long press
  (since it was never started)

Fixes: 307254136
Test: Enable 3p launcher and invoke omni
