Fix QS bluetooth tile accessibility issue

Bluetooth tile was not announcing its state when the top half was
clicked.  This is because if handleUpdateState was triggered on
the view before it became dual then it would not get all of the dual
accessibility information.  So if the dual state changes on a tile
make sure to call handleUpdateState so it can be handled appropriately.
