Our fuzzing setups don't work in a proper repository, but only use the
in-memory configured `the_repository`. Consequently, we never go through
the full repository setup procedures and thus do not set up the hash
algo used by the repository.

The commit-graph fuzzer does rely on a properly initialized hash algo
though. Initialize it explicitly.
