    display: Correctly select "single" mode when opening display panel
    
    The dialog tried to retain the current configuration mode. However,
    doing so means that we end up in the wrong mode in some situation (e.g.
    opening the dialog with two displays but only one enabled).
    
    Fix this by always selecting a configuration mode. This potentially
    switches the user from "join" to "single" if only one monitor is left.
    However, the user has no way to do this manually, so no unexpected UI
    change will happen.
