Fix several places where md-using relays would get wrong behavior.
This patch replaces a few calls to router_get_by_id_digest ("do we
have a routerinfo?") with connection_or_digest_is_known_relay ("do
we know this relay to be in the consensus, or have been there some
time recently?").
Found while doing the 21585 audit; fixes bug 23533. Bugfix on
0.3.0.1-alpha.
