The core issue is in rails, where the migrations_paths get initialized before the rails environment,
when calling db:create, and it's not getting update later

https://github.com/rails/rails/blob/v5.0.0.1/activerecord/lib/active_record/railties/databases.rake#L16

Steps to reproduce

1. install a plugin
2. rake db:drop db:create db:migrate
3. notice the plugin migrations are not being run
