#check_validations(context = :default) ⇒ Object

everything works the same if this method isn’t overwritten with a no-op however, i suspect that this is the case because the registered before(:save) hook somehow gets lost when overwriting Resource#save here in this module. I’ll leave it in for now, to make the purpose clear
