    lib: Fix "Bluetooth Off/Turn Off" wedged state in gnome-shell
    
    When the adapter was set to be the new default, nothing was telling
    gnome-shell, which only listens to the "row-changed" signals for
    updates, that there was a new default adapter, so it was stuck in the
    off position ("Bluetooth Off" menu header), but rfkill correctly said
    that a Bluetooth adapter was available and offering to turn it off
    ("Turn Off").
