git-checkout: disallow --detach on unborn branch
abe199808c (git checkout -b: allow switching out of an unborn branch)
introduced a bug demonstrated by
git checkout --orphan foo
git checkout --detach
git symbolic-ref HEAD
which gives 'refs/heads/(null)'.
This happens because we strbuf_addf(&branch_ref, "refs/heads/%s",
opts->new_branch) when opts->new_branch can be NULL for --detach.
Catch and forbid this case, adding a test to t2017 to catch it in
future.
