[gnome-control-center/wip/carlosg/ethernet-dialog-crash] network: Keep a ref on NetDeviceEthernet while a edition dialog is open

    network: Keep a ref on NetDeviceEthernet while a edition dialog is open
    
    Otherwise, invoking other panel (eg. through shell search, or CLI) and
    closing the dialog will result in a crash, as the NetDeviceEthernet
    object does no longer exist.
