I ran into an issue where concurrently creating new tenants in async tests crashed due to ash_postgres attempting to concurrently compile the same tenant migration file.

Notes
I attempted to write a regression test as well, but came to the conclusion that it would end up being brittle since it is timing-based and needs multiple DB connections. It would also require me to add a whole new domain with context-based multitenancy instead of attribute-based to the test repo.
