    remote-desktop: Only ask for streams if SelectSources was called
    
    The remote desktop dialog has a screen cast widget in case remote
    desktop session was made into a hybrid remote desktop / screen cast
    session by calling org.freedesktop.portal.ScreenCast.SelectSources on
    the remote desktop session object.
    
    This was done by checking the selected screen cast list elements when
    the dialog was done. With the port to GTK4 items were selected by
    default; what this accidentally resulted in was the remote desktop
    always attempting to open screen cast streams without the user ever
    having seen the widget, as even if it wasn't made visible, it was still
    constructed as part of the template, only not made visible.
    
    Fix this by only attempting to create streams if the SelectSources
    method had been called.
