Removed the notifyDataSetChanged from setItems

NOTE: If you are updating from v2.4.0 to v2.4.1,
note that the setItems(items) method has removed the notifyDataSetChanged()
and you need to call it by yourself.

/**
 * Update the items atomically and safely.
 * It is recommended to use this method to update the data.
 * <p>e.g. {@code adapter.setItems(new Items(changedItems));}</p>
 *
 * <p>Note: If you want to refresh the list views, you should
 * call {@link RecyclerView.Adapter#notifyDataSetChanged()} by yourself.</p>
 *
 * @param items The <b>new</b> items list.
