Moved activity to stopped state if relaunched while device is asleep

- If an activity is done relaunching and the device is sleeping or
shutting down, go ahead and force the activity to sleep which will
transition it into the stopped state. We do this after the activity
is relaunched as activities can currently only relaunch into the
resumed or paused state both of which are visible state.
However, the activity should be in the stopped state while the device
is sleeping.
- Also removed previous fix for b/28518380 that prevents activities from
relaunching due to configuration changes while the device is sleeping.
We need to allow relaunches due to configuration changes while the device
is sleeping so the things are responsive when you wake-up the device.
And, it is no longer a big deal since we are transitioning the activity
to the stop state when the relaunch is complete.
