* When finalising paired packages, cope with there being multiple choices
For ordinary packages we selected a single version which means
we added an equality constraint. As a consequence we used to
assume there was only one version left when finalising. For
paired packages there may be two versions left if the package
did not directly constrain the choice to just one. If there is
more than one version remaining then we have to pick between
them. At the moment we still pick the highest version, but
later we can take a global preference or polciy into account.
