Don't use gtk_menu_item_set_submenu() with NULL menu with GTK+ < 2.12.

Browse Source 
In GTK+ 2.10 and earlier gtk_menu_item_remove_submenu() had to be used to
remove the items submenu as gtk_menu_item_set_submenu() gave errors when
passed NULL submenu, so call the old function when using old GTK+ version.
