fix(decorator-util): uncomment error

when testing with one of our production apps (gi-kis) we have two models (OrderLinkedForm & CoverSheetForm) which define both the same index FORMS_ORDER_ID_TYPE and extend Form and BaseForm, an error will occur when decorators are executed, this should work.
for now we just uncomment the error
