Comment # 5 on bug 938955 from Josef Reidinger

It is proposed at
https://github.com/yast/yast-services-manager/blob/master/src/lib/services-manager/clients/default_target_proposal.rb#L235

I also do some fixes in this area when switching to role based desktop
selection.

Christopher: can you please retest or if you do not have time, please close.
Thanks
