    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.
