git-remote-mediawiki: update tests to run with the new bin-wrapper

Until now, if git-remote-mediawiki was not installed, the test suite
copied it to the toplevel directory. This solution pollutes the
directory with untracked files. Plus, we would need to copy the new
git-mw.perl file to test it too.
