function combo_field_storage_query not called, drupal uses mongodb

Solution: update {system} table at combo_field_storage_install and set weight of this module greater then any field_storage module has and clear some caches (at this moment i do not know exactly which - i used phpmyadmin and admin_menu for that after module installed and i found problem).

(because mongodb_field_storage_entity_query_alter($query) is called after combo_field_storage_entity_query_alter($query) when both have weight = 0).

(probably i didnt found that but i need to change combo_field_storage_query for my purposes)
