I am doubtful that anyone cares if 'ls branches' might include branch
names that only exist in invalid certs -- at the moment, there isn't
even any sane way to *have* invalid certs.  I don't care, myself, and
am perfectly happy to leave it broken until a user actually notices.

If one really does want to get 'ls branches' exactly correct in that
case, the right way isn't to do expensive head-calculation anyway.
All we need to know is that there is some valid branch cert out there
somewhere, and we can tell that by just pulling a cert out of the db
and checking it, which is very cheap.
