    powerProfiles: Avoid warnings on missing power-profiles-daemon
    
    GDBusProxy transparently handles the remote object appearing and
    vanishing. It is therefore not an error if the service is not
    running at the time the proxy is initialized, so we proceed and
    try to read the list of profiles which is null in that case,
    resulting in (harmless but annoying) warnings.
    
    Avoid this by only reading the initial list of profiles if the
    service has a name owner.
