Do not unref GtkWidget of unattached wxMenuBar.

Browse Source 
This results in the destruction of the widgets of all of its menu and when
wxMenu objects are themselves destroyed in the base class dtor, we try to
destroy their already destroyed widgets, resulting in critical GTK warnings.

Simply don't do anything in wxMenuBar dtor itself if the menu bar is not
attached to a frame as the workaround was only needed in case of destroying
attached menu bars.
