/**
 * Determines the appropriate menu item ID based on the current ActionBar title.
 *
 * This function serves as a workaround solution because not all drawer menu item
 * navigations extend from DrawerActivity and back button changes content but not the drawer menu item.
 * As a result, the content and highlighted
 * menu item may not always match. This function helps maintain consistency between
 * the displayed content and the highlighted menu item.
 *
 * @return The menu item ID corresponding to the current ActionBar title, or null if
 *         the ActionBar is not available.
