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.
