[bridgedb/master] Dump bridges to file, despite lack of BridgeHistory

commit f5fe05ce61d0e18bf00638e2eb1fdda785fe4c81 Author: Matthew Finkel <Matthew.Finkel(a)gmail.com> Date: Sun Aug 3 17:40:53 2014 +0000 Dump bridges to file, despite lack of BridgeHistory We only dumped the bridges assigned to buckets if we had bridgehistory for them.
