don't attempt a resolve when the cached answer will do 

For relays that don't know their own address, avoid attempting
a local hostname resolve for each descriptor we download. Also cut
down on the number of "Success: chose address 'x.x.x.x'" log lines.

Fixes bugs 20423 and 20610; bugfix on 0.2.8.1-alpha.
