[Rails 5] It requires actable when belongs_to_required_by_default is true

[wbotelhos]

When option: config.active_record.belongs_to_required_by_default is true, it ask about actable:

ActiveRecord::RecordInvalid: Erro de validação: Actable translation missing: pt-BR.activerecord.errors.models.event.attributes.actable.required!

I imagine that the actable_id is filled after save the child, but in some way, it is validated before.

config.active_record.belongs_to_required_by_default = true

class Event < ApplicationRecord
  actable
end

class Exam < ApplicationRecord
  acts_as :event
end

Exam.create!

Is this still the case with the latest version of this gem?
