Restore the behavior of adding a RESUMED activity to stopping list

Revert part of 9b8ece20 because of b/169190153.

Also this makes the activity starting pausing while resuming it
if the activity is started while screen off, see
Task#resumeTopActivityInnerLocked where the RWC#ensureVisibilityAndConfig
was called after activity state set to RESUMED.
