Run screen off controller on rotation

The screen off controller is responsible for setting up the correct
status bar state prior to any animation running. Without this,
the device will flash notifications on power off from landscape
(app or launcher). The actual animations continue to run
in GoneToAodTransitionViewModel.

Just remove some existing code.
