    lib: Fix possible crash when UPower updates
    
    Due to a reference leak, libupower-glib could still callback into our
    BluetoothClient even if it was already finalized as the signal handlers
    were not forcibly disconnected when the BluetoothClient was.
    
    See https://gitlab.freedesktop.org/upower/upower/-/merge_requests/112
