Update test to avoide being dependent on git configuration

The previous test implementation was dependent on the git configuration:
	renames = copies

It could then pass on a computer with that config but not passe on
a different developpeur computer who could have a different git configuration.

That new implementation is testing the same behaviour but at a lower
level and is not dependent on the git configuration anymore.
