[PATCH v3 6/6] remote: add test for negative refspec with prune

[Jacob Keller <jacob.keller@gmail.com>]

git remote prune does not handle negative refspecs properly. If a
negative refspec got added after a fetch, a user may expect that the
resulting refs that were previously fetched would now be considered
stale, and thus removed by git remote prune. Show that this isn't the
case with a new test case.
