    settings-widget: Fix duplicate device when bluetoothd restarts
    
    As recommended in the BluetoothClient documentation:
    "
     Note that #BluetoothClient::device-removed will not be called
     for each individual device as the model is cleared when the
     #BluetoothClient:default-adapter property changes.
    "
    
    Closes: #116
