Run transition when app dies in freeform

In a freeform environment, currently a shell transition times out when
an app is killed via adb force-stop.

In this timeout case, setReady() isn't called where it's supposed to
because handleAppDied doesn't directly trigger any z-order or focus
update in freeform mode.

This CL adjusts the if condition in question so that this kind of
lingering transition will be executed even without any focus change.

This CL also fixes the timeout issue when dismissing placeholder activity and a PIP task is there.
