Just to confirm that this works correctly, because I broke it a few
times in different ways while working on T321121.
In this scenario, discussiontools_item_revisions contains rows for
the oldest and newest revisions of pages containing each comment
distinguishable by name, as well as extra rows for the newest
revisions of comments indistinguishable by name, so that they can
be looked up by ID.

discussiontools_item_pages row itp_id=5 has incorrect
itp_oldest_revision_id. It should point to the older of the two
revisions with the same time, but it points to the newer one.
discussiontools_item_revisions row is missing.

Many methods are covered indirectly, and using method-level
@covers filters means these are reported as not being covered.
