- Convert an assert in the pathbias code to a log message. Assert
appears to only be triggerable by Tor2Web mode. Fixes bug 6866;
bugfix on 0.2.3.17-beta.

+ by Tor2Web clients allows hidden services to identity tor2web
+ clients through their repeated selection of the same rendezvous
+ and introduction point circuit endpoints (their guards).
