FIX #526: Do not depend on test-sources by ankostis · Pull Request #527 · gitpython-developers/GitPython

There is something fishy going on...I just amended and re-pushed the commit, and still in the Appveyor I'm getting a commit-id that I do not have it in my local repo: cc096ddf

Clicking on to it I see that it is a merge commi, only present on GitHub - but this PR is not yet merged, and actually it is explicitly not based on the latest master, to avoid errors from #513. But this "automatic merge" behavior is defeating my goal.

@ Byron any idea why this is happening?
