Summary: Ref T13048. This migration is from January 2012 and probably only impacted Facebook. It references `HeraldRepetitionPolicyConfig`, which I'd like to change significantly. I initially just replaced the constant with a literal `0`, but I don't think there's any actual value in retaining this migration nowadays. The cost of removing this migration is: if you installed Phabricator before January 2012 and haven't upgraded since then, you'll have a few more rows in the `APPLIED` table than necessary. Herald will still work correctly. Test Plan: Reading. Reviewers: amckinley Reviewed By: amckinley Maniphest Tasks: T13048 Differential Revision: https://secure.phabricator.com/D18924
