Hans Lindgren 0360e4c93d Cleanup before removal of conductor local apis
Some old cruft from the when conductor proxying was being used to
make db calls are left in various places in unit tests. None of this
is of use anymore and needs to be removed before the conductor local
apis and related 'use_local' flag can be removed.
