t/helper: initialize repository if necessary

The repository helper is used in t5318 to read commit graphs whether
we're in a repository or not. However, without a repository, we have no
way to properly initialize the hash algorithm, meaning that the file is
misread.

Fix this by calling setup_git_directory_gently, which will read the
environment variable the testsuite sets to ensure that the correct hash
algorithm is set.
