This can be turned off by setting `config.reload_classes_only_on_change` to false.
Extensions like Active Record should add their respective files like db/schema.rb and db/structure.sql to `config.watchable_files` if they want their changes to affect classes reloading.
Thanks to https://github.com/paneq/active_reload and Pastorino for the inspiration. <3
This handles the case where config.cache_classes is true and classes
are loaded before the I18n load path has had a chance to be populated.
