If argument of `build_record` has key and value which is same as default value of database, we should also except the key from `create_scope` in `initialize_attributes`. Because at first `build_record` initialize record object with argument of `build_record`, then assign attributes derived from Association's scope. In this case `record.changed` does not include the key, which value is same as default value of database, so we should add the key to except list. Fix #21893.
