In the recent update from libgit2 1.1.x to 1.3.x, something seems to
have changed upstream. Resulting in the clone of a branch ending up
with a semi-bare file system state (in other words: without any files
present in the directory).

This commit patches the clone behavior to set the CheckoutForce
strategy as CheckoutOption, which mitigates the issue.

In addition, test cases have been added to ensure we do not run into
this again by asserting the state of the branch after cloning.

Fixes: #588

If there is no configuration set for `init.defaultBranch`, it does not
return an error but an empty string. We now take this into account so
we do not overwrite the default, and make the default `master` to match
with libgit2 defaults.

In addition, some comments have been added to not get confused about
what commits we are checking against.

Can we add a test for a YAML file that we place in Git, then check that the file in the artifact contains the exact same YAML content as the one in Git?

@stefanprodan it would be better to add this in rewrite-dev as none of the tests in main will remain.
