security: Correct KeyChain::addCertificate semantics

The documentation of KeyChain::addCertificate was ambiguous.  On the one
hand, it stated that the certificate with the same name will be
overwritten. On the other hand, it stated that it will thrown an
exception if certificate with the same name exists.  This commit ensures
the former behavior, which is consistent with the old KeyChain.
