The test_server in this unit test should also have a
ssl_options.signed_cert_timestamp as in the previous test, so that the only
difference between the two tests is whether the client advertises the TLS
extension or not.

Good point - I wanted to test that no "SCTs" were mistakenly set - but this way
we also cover that no SCTs were requested. Done.
