model callbacks fail if referenced models not prepended with `::`

Expected behavior

Referencing related models in callbacks doesn't cause any issues.

Actual behavior

I have a method in a model Behavior that creates related records that is called in an after_create callback.

      if EngagementQuestion.count.zero?
        EngagementQuestion.create!(
          position: 0,
          behavior: self,
          organization: Organization.current
        )
      else
        EngagementQuestion.create!(
          position: EngagementQuestion.maximum(:position) + 1,
          behavior: self,
          organization: Organization.current
        )
      end

Whenever I create the behavior using forest, in development I get ArgumentError Exception: A copy of Behavior has been removed from the module tree but is still active!, in production I just get "Unknown Error". I have noticed that if I prepend every model with :: (i.e. ::EngagementQuestion) I can at least get past this, but it still fails because the behavior contains translations that are automatically created by the globalize gem in a separate callback, and this fails as well (I'm assuming for the same reason)

I can confirm that this does not happen in Rails 6.1
