Bug#20411: "GRANT ... REQUIRE ISSUER nnn AND SUBJECT mmm" fails to require both

when X.509 subject was required for a connect, we tested whether it was the right
one, but did not refuse the connexion if not. fixed.

(corrected CS now --replace_results socket-path)

  Bug#20411: "GRANT ... REQUIRE ISSUER nnn AND SUBJECT mmm" fails to require both
  
  test not only whether we can connect with a correct X.509 subject when one is
  required, but also assure that we can't without one.

  actually refuse connexion if X.509 is required, but does not match. kudos to Al Smith.
