SecureTransport: handle NULL trust on success The `SSLCopyPeerTrust` call can succeed but fail to return a trust object if it can't load the certificate chain and thus cannot check the validity of a certificate. This can lead to us calling `CFRelease` on a `NULL` trust object, causing a crash. Handle this by returning ECERTIFICATE.
