git-codereview: clean up detached HEAD mode

Long ago I decided to return origin/HEAD from b.OriginBranch
in detached HEAD mode, thinking it would cause obvious failures.
But the joke was on me - origin/HEAD is a real thing in git,
and HEAD tracking origin/HEAD is not the right answer on dev branches.

Now that each branch's codereview.cfg typically has the branch info
we need, we can use that in detached HEAD mode to be able to provide
useful displays in commands like "git pending". And we can be careful
not to do that when we don't know the actual branch.

This commit cleans all that up.
