[tor/release-0.3.1] Fix several places where md-using relays would get wrong behavior.

commit e05414d2411a5354dc43bde3a791938697a9799b Author: Nick Mathewson <nickm(a)torproject.org> Date: Wed Sep 6 16:26:47 2017 -0400 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.
