test(golang): the repeated-output case in TestValidateRefusals breaks only that rule

The "output twice" case had no Kind, so Validate refused its first
Equality under the untyped rule and never reached the second: deleting
the "asked for twice" check left every test passing. The case is now
typed UInt32, and a second assertion checks that the repetition is what
the error names.
