always start certmonger during IPA server configuration upgrade
    
    This patch fixes a regression introduced by commit
    bef0f4c5c38e7ff6415e8f8c96dc306ef7f0ce56. Instead of checking whether
    there is CA installed in the topology, we should always start certmonger
    service during upgrade regardless when CA was configured.
