Fixing a couple nav bar crashes
- Reset the rotation button controller callback when detaching the nav
bar (the callback can otherwise be called back)
- Only touch autohide if the controller is set (RotationButtonController
update callback is set when initialized and not unset, so it too can
callback into the nav bar view after it's been destroyed)
- Add workaround for issue where content provider can still callback
the observer after the observer has been unregistered, but the msg
has been posted to the handler (filed b/198002034 to track fw fix)
