 * Implements hook_pre_features_revert().

 * If a menu link is added in a menu handled by this feature, it won't be deleted when the menu feature is reverted.
 * Only the menu links exported in the feature will be reverted.
 * Implementing this hook allows us to make sure that the menu is fully resetted after the revert
 * by first deleting all menu links before reverting.
