Some of deleteArchivedFiles.php and deleteArchivedRevisions.php were
split off to deleteArchivedFiles.inc and deleteArchivedRevisions.inc
respectively in r62948 (04b2413aac) for use in tests.
The tests no longer use those methods, so I moved them back and inlined
them into execute(). I also did some minor cleanup -- changing direct
calls to tableName() and query() to use query builder functions and
clarifying/fixing some of the logic that was in deleteArchivedFiles.inc.
