    Fix visual glitches on startup
    
    When the dialog first appears, you can see the window title change from
    gnome-volume-control to "Sound Preferences". Also, the output volume
    slider visibly gets its initial allocation wrong.
    
    This is due to showing the dialog out of its constructor.
