add -q to git symbolic-ref call
Avoids a warning message from git when HEAD doesn't exist. Which it won't
when eg, git-annex is used in a submodule just cloned with
git clone --recursive. In this case, a specific ref is checked out and
there's no HEAD yet.
The code already returned Nothing in this case, so no behavior change other
than not showing the warning. And git-annex operates fine in this
situation.
