This is a regression since d2623129a7de ("qom: Drop parameter @errp of object_property_add() & friends"). The first patch fixes the issue and the second patch adds a test to check the error is gracefully returned to the QMP client. The last patch can be considered independently. It merges all the object-add tests into a single test function and cover new failure cases.
