sync: Fix committing when in a direct mode repo that has no HEAD ref.
Seen for example, a newly checked out git submodule. In this case, .git/HEAD is a raw sha, rather than the usual reference to a ref. Removed currentSha in passing, since it was a more roundabout way of doing what headSha does, and headSha is more robust.
