Log:
Bugfix on r13098. Backport candidate.
When we made bridge authorities stop serving bridge descriptors over
unencrypted links, we also broke DirPort reachability testing for
bridges. So bridges with a non-zero DirPort were printing spurious
warns to their logs. Bugfix on 0.2.0.16-alpha. Fixes bug 709.
