more_data field exists in migration but not in db

Dang, I was hoping it would be an easy fix.

If you make a PR with your changes I’ll review it and merge it in.

As for making sure this doesn’t break in the future, since these issues were caught by Django’s checks framework, I’m thinking I can just make an app with custom/swapped models and run Django’s check management command.
