test_objagg: Uninitialized variable in error handling
We need to set the error message on this path otherwise some of the callers, such as test_hints_case(), print from an uninitialized pointer. We had a similar bug earlier and set "errmsg" to NULL in the caller, test_delta_action_item(). That code is no longer required so I have removed it.
