Refuse to fetch into the currently checked out branch of any working

Fixes this previously reported bug:

As a side effect of using find_shared_symref, we’ll also refuse the
fetch when we’re on a detached HEAD because we’re rebasing or bisecting
on the branch in question. This seems like a sensible change.

Missing tests though, would be nice to have a test that saw what
happened when the branch is in that "git bisect start" or rebasing
state.

Also what those commands to if the branch is updated, e.g. with
git-update-ref.
