This only validates that if a test and its fork exist that the CL touches both. There are lots of other cases we could imagine checking like if you *add* a new test on one side, you should one on the other. But those are likely to have a lot of false positives now while the migration is happening and new NNBD tests are being written. So for now, this just tries to check that tests that have been forked at least don't diverge. It's a start.
