embedded_migrations::revert missing

[agentsim]

After generating migrations with embed_migrations!, the resulting module does not include the revert method.

I would like to revert and then run migrations before each unit test, guaranteeing a clean database before each test invocation.

We've purposely excluded the revert method, because what it does is dependent on which migrations have or haven't been run, and we don't expose that information.

Dropping and recreating your database is not recommended for tests. Instead, you should run your tests in a transaction. We provide begin_test_transaction and test_transaction for this purpose.
