Tenant migrations not run with rails db:prepare

[archonic]

Rails 6 introduced rails db:prepare which runs safely runs db:create, db:seed and db:migrate. This is especially helpful for deploy scripts that don't need to be aware if they're being run for the first time or the Nth time.

I've found that rails db:prepare only runs migrations in the public schema. If I can find the time, I'll submit a PR to fix this.
