testCertificateAuthorityTool: skip test_person_request_certificate_twice

This feature of configuring openssl to disallow issuing more than one
certificate for the same common name as been disabled in SlapOS'
certificate_authority recipe, but instead of fixing this, we decided
to disable this test until the tool is completly rewritten using
caucase.
