Don't resume until keyguard is gone

If we try to resume top activity immediately after we remove
the sleep token and something else in the system will call
ActivityStackSupervisor#ensureActivitiesVisibleLocked(), then
the activity will be immediately stopped. This not only introduces
an extra unnecessary cycle, but also leads to other with
activities ending in a wrong state or cycling through states
indefinitely.
