Don't obsolete a very-new connection for having no circuits yet.
This fixes the last known case of bug 891, which could happen if two
hosts, A and B, disagree about how long a circuit has been open,
because of clock drift of some kind. Host A would then mark the
connection as is_bad_for_new_circs when it got too old and open a new
connection. In between when B receives a NETINFO cell on the new
conn, and when B receives a conn cell on the new circuit, the new
circuit will seem worse to B than the old one, and so B will mark it
as is_bad_for_new_circs in the second or third loop of
connection_or_group_set_badness().
Bugfix on 0.1.1.13-alpha. Bug found by rovv.
Not a backport candidate: the bug is too obscure and the fix too tricky.
