[gnome-bluetooth] settings: Emit adapter-changed-signal

[Bastien Nocera <hadess src gnome org>]

commit c24cd2427e9927a7f695aedd17576ed3ca412a17

    settings: Emit adapter-changed-signal
    
    When the default adapter changes, or when it gets powered on.
    
    This will allow the Bluetooth settings panel to monitor the status of
    transitioning adapters, when Bluetooth rfkill is disabled, but the hciX
    adapter is unpowered/rfkilled.
