naviframe: Fix elm_naviframe_item_pop_to not to attempt to remove removed item

Summary:
Previously, the following error message is shown.
         eina_inlist_remove() safety check failed: item does not appear to be part of an inlist!
         Now, eina_inlist_remove() is removed from elm_naviframe_item_pop_to
         because eina_inlist_remove() is called in _item_del_pre_hook.
