Subject: Kill warn when picking bridges without bw weight
Commit: 303beead53c24cfc2b48a0873950f46beb6d8e58

Bridges and other relays not included in the consensus don't
necessarily have a non-zero bandwidth capacity. If all our
configured bridges had a zero bw capacity we would warn the
user. Change that.
