erp5_certificate_authority: Include parent reference for backward compatibility

   This code is only required until the slapos.core relies on the certificate text to extract the COMP-* reference.

    This change shouldnt be merged on main branch of erp5 code base, since it is a pure backward compatibility for a single type of user. I dont think we should make it more flexible neither since the need should be gone on the next releases of slapos-node packages.
