Tweak the leaf pattern used when computing the "why" pane so that it displays useful results for removed and newly installed packages.

The problem was that it was only looking at package versions that were
currently installed / going-to-be-installed.  Instead, this matches
the current version of a package and the candiadte version (if the
candidate will be installed).
