Basically, the way that we had setup our repositories was messy (both because they were added with an ugly callsign and because they were created by inserting rows directly into the DB), and so I deleted the repositories (`./bin/repository delete`) and re-added them. However, now there are lots of "Unknown Object"s where previously a commit was linked.
Is there an easy way that I can purge these unknown objects?
Admittedly, our version of Phabricator is a bit old (maybe 6 months). I am upgrading it soon.
