git-gui: Don't offer tracking branches if none exist.

I refactored the common code related to tracking branch listing into
a new procedure all_tracking_branches.  This saves a few lines and
should make the create and delete dialogs easier to maintain.

We now don't offer a radio button to create from a tracking branch
or merge-check a tracking branch if there are no tracking branches
known to git-gui.  This prevents us from creating an empty option
list and letting the user try to shoot themselves in the foot by
asking us to work against an empty initial revision.
