Allow switching keyboard layout to null. Previously, PersistentDataStore#switchKeyboardLayout doesn't allow switching keyboard layout to null, which means default layout. As a result, when no keyboard layout is corresponding to the new subtype, previous keyboard layout continues to be used on switching subtpyes.
