Get deleted page creations of user

Used to get the pages created by a user that have since been deleted.

Note that this query requires post-processing. Due to the way the `archive` table works, multiple log entries may be returned, causing the same ar_id to appear twice here. The receiving end must use post-processing to (1) match the correct `log_page` to `ar_page_id`, if the latter is not null, or (2) find the first logged deletion since after the page was created. The `` pd.`log_timestamp` > `ar_timestamp` `` clause here discards unlikely data to make this a tad faster.
