repo: Use the worktree when checking the repo rev.

Avoids treating the operation as if it were acting on a bare repository, thereby triggering failures when the Git client is configured with `safe.bareRepository=explicit`. Repo doesn't actually use a bare repository, but pointing at the gitdir acts as if it had.
