For non-patches the - in this case correctly determined sat::Solvable - is
converted into the corresponding ui::Selectable::updateCandidateObj.

Or for non-zyppers: The solver computed 'libvlc5;2.1.5-114.3;x86_64;VideoLAN'
is converted into the 'best' libvlc5 available (highest version but same arch
and vendor as the installed one).


Is there a way to tell, whether the packageIDs passed to
  backend_update_packages_thread 
were (correctly) determined by a previous call to 
  backend_get_updates_thread 
or whether it's the 'only allow to update candidates (fdo#61231)' case?
