To fully support wikibase changes in the watchlist, we need to insert a null revision and have a unique revision id to insert into the rc_cur_id field of the recentchanges table.
It may be possible to use a hacky GROUP_BY clause in the watchlist query, a subquery, or other uglyness to make it work without the null revision, but that would make the watchlist query a bit slower.
