fix errors setting up new database

[billneff79]

Due to the order that the database migrations were being run in, a brand-new database setup would fail when running migrate-to-local-times because the model was trying to use a postUpdatesInChannel field that isn't present in the database yet. By changing the file names in this PR, the postUpdatesInChannel field gets added before it is used by ``migrate-to-local-times` and the databases get setup properly now, even on a fresh install
