Pathbias should continue to ignore previously ignored circs.

If circuit padding wants to keep a circuit open and pathbias used to ignore
it, pathbias should continue to ignore it.

This may catch other purpose-change related miscounts (such as timeout
measurement, cannibalization, onion service circuit transitions, and
vanguards).
