When we're checking the repository's format, set the hash algorithm at the same time. This ensures that we perform a suitable initialization early enough to avoid confusing any parts of the code. If we defer until later, we can end up with portions of the code which are confused about the hash algorithm, resulting in segfaults when working with SHA-256 repositories.
