* Write a failing test for reloading with Spring
This test captures what I think is going on in
https://github.com/thoughtbot/factory_bot_rails/issues/323
Currently the factory_bot_rails reloader only reloads factory
definitions when the definition files have changes (using
`execute_if_updated`).
This can cause problems when editing an application file without also
editing a factory_bot definition file. Rails will reload the entire
application, but will not reload the definitions. This causes
factory_bot to have references to classes that were unloaded from the
Rails application and replaced with new classes.
https://github.com/thoughtbot/factory_bot_rails/pull/329 replaces
`execute_if_updated` with `execute` so that factory_bot_rails will
reload the definition files whenever anything in the application is
changed. Hopefully that PR will get this test to pass!
