Subject: [PATCH 2/3] Sort certificates by ID

This is needed to avoid non-deterministic order of the certificates in
case the underlying pkcs11 module does not guarantee that (such as
softhsm). Without this change, the signing and encryption certificate
might get mixed up and application might try to use wrong one for
verification or decryption.
