A way to reproduce the conflict between REMOTE/Git and convert/generateTests goals

gistfile1.txt

How to reproduce :
clone this repo https://github.com/magelle/devoxx2020-contract-testing
in inventory project run Spring Cloud Contract plugin : No problem

You can then create a git repository. A local one is good enough, like explained [there](https://github.com/magelle/devoxx2020-contract-testing/blob/master/README.md#part-2)

You can add the following configuration :

                    <contractsMode>REMOTE</contractsMode>
                    <contractsRepositoryUrl>git://file:///Users/ygrenzinger/git/test.git</contractsRepositoryUrl>
                    
You can now run pushStubsToScm goal of the plugin and the contract will appear in the master branch of the repo as expected (after a git pull).

But now as soon you try to run the convert or generateTests goals. The following errors appear:
