    tests: Enable dconf service for new dbusmock compatibility
    
    python-dbusmock will also stop importing all session services that are
    installed on the host system by default (as is already the case for
    system services). With this change, the dconf service cannot be
    activated anymore unless we explicitly enable the service in the
    environment.
    
    Add the appropriate call to enable the service, guarded by a check that
    the method exists to be compatible with older dbusmock versions.
