Description

Now that we have https://issues.apache.org/jira/browse/KAFKA-12234 merged into trunk and 3.0, we have to ensure that we test for the case where we have the same group id appearing in the request more than once and handle it correctly in batched OffsetFetch requests. Generally speaking we wouldn't expect this to happen since we wouldn't allow this for requests being built from the Builder, but it would still be good to have a test for this.
