[repository] refactor/cleanup entity deletion methods * kill unused Repository.delete_info_multi (no leading _) * kill unnecessary system_source.delete_info (almost no benefit over delete_info_multi) * stop giving entities list *and* extid list, gather them from the entity when needed * move pending eids handling into glob_delete_entities, so one can call it directly without worrying about that
