Fix a bug where an unreachable relay would establish enough
reachability testing circuits to do a bandwidth test -- if
we already have a connection to the middle hop of the testing
circuit, then it could establish the last hop by using the existing
connection. Bugfix on 0.1.2.2-alpha, exposed when we made testing
circuits no longer use entry guards in 0.2.1.3-alpha.
