Make the transition sleep failsafe stricter

The original check was too lenient and assuming that the handlers
would finish. However, this is supposed to be a hammer so make it
always go down the force path if there is any other transition
playing or ready.

Bug: 267738124
Test: sleep while animation is playing.
