Description:

Minor gnutls cert cleanup.

Don't use the purple_certificate_get_unique_id and
purple_certificate_get_issuer_unique_id. We can just use our
x509_cert_dn and x509_issuer_dn functions directly. It's stupid to call
out to the libpurple certificate code only to have that code call a function
in our plugin code--instead, just call the plugin code directly.
