Update property translation domain dict everytime we add a new property sheet. This fixes test_translated_accessors who was working until 30866 because _property_domain_dict was not included in the business template.

This fix is only partial, because if property sheet definition change or if new property sheets are added on the class, the domain will not be recalculated.
