Run TaskDisplayArea recovery during sleep tokens

In AOD we can have a showWhenLocked activity visible but
put to sleep by the Keyguard sleep token. Checking for
isSleeping stops us from recovering display area visibility
when:

- AOD is active
- A showWhenLocked, non-turnScreenOn app starts to launch
- Post-collect, app calls recreate(), adds FLAG_TURN_SCREEN_ON
- App becomes visible in relayout
