Queries on logging-table perform different on different wikis. 
Atm there are different key definitions on eg. enwiki and dewiki
- enwiki has a key `log_user_text_time`(ok to have), dewiki doesn't
- dewiki has a key `log_user_type_time`(important to have), enwiki doesn't
- same for `log_title_time` / `log_page_id_time`
