Summary: Ref T11114. Ref T12085. I missed a few pieces of cleanup when moving all this stuff over. In particular, load all fields which use Custom Field storage before doing commit-message-related stuff, instead of just the ones that claim they appear on commit messages. Test Plan: Edited revisions and made API calls without apparent issues. See followup on T12085, shortly.
