git clone is creating a destination empty directory before even
attempting to clone the remote URL. It means that if the user-supplied
remote URL happen to be invalid, an empty directory is getting created
at dest, preventing us to try cloning the same repository once again.
We fixed that issue by checking whether the remote git repository
exists using git ls-remote **before** calling git clone.
git ls-remote will fail on a git repository not containing any git
commit. We add a function to the test bed creating a git repo with one
commit. It's a bit hacky, but that's the best setup I could come with.
We embed a dummy git repo to the my-repo-pins codebase and copy it
during the test phase to a tmp workspace.

Using a single letter name was a mistake. Renaming the project to
something a bit more sensible. Maybe not too sensible that being said:
we had to adopt a pun.
Kudos to Wiwi for the pun: it's perfect.
