The test relies on things ending up in the h2RequestsToSend container
internally. For h2c we would have to use the http1 upgrade mechanism,
and while I have not verified it, it seems to not reliably put
enough requests in the container, and so the test is flaky for macos,
which is the only platform where we use h2c. In CI at least.
Fix it by forcing it by using h2 direct, which will work even on macOS
without server-side ALPN.
Pick-to: 6.7 6.5 6.2
