Update broken javadoc code ref. Use class fully-qualified class name

     * order to make sure shortcuts exist and are up-to-date, without the need to explicitly handle

     * the shortcut count limit.

     * @see android.app.NotificationManager#notify(int, Notification)

     * @see Notification.Builder#setShortcutId(String)

     * @see android.app.Notification.Builder#setShortcutId(String)

     *

     * <p>If {@link #getMaxShortcutCountPerActivity()} is already reached, an existing shortcut with

     * the lowest rank will be removed to add space for the new shortcut.
