Replace display area organizer upon registration

- Checking for binder aliveness is prone to races which can cause a
  crash if SysUI is restarted quickly.  There hasn't really been an
  issue with multiple processes organizing the same display area
  feature, and we can clean up the previous organizer cleanly, so
  this change defaults to that behavior (it still logs)
