    extensions-app: Explicitly dispose window when removed
    
    Unlike in previous GTK version (or Clutter), destroy() no longer
    breaks reference cycles but just releases the reference held by
    GTK itself.
    
    So any reference we hold - either the explicit property or any signal
    handlers that bind the window as `this` - prevents the window from
    being disposed when closed, and the application won't quit.
    
    Work around this by explicitly running dispose() on the window when
    it is removed from the application.
