Change integration test to not bother tor

Everytime we spin up a CI node for testing, we are registering to the tor network, and if we do quite a few of these, we trigger alerts, so it would be good if we didn't trigger those alerts.

We can either use chutney for LEAP integration tests, for example OnionBalance and https://github.com/TheTorProject/bwscanner/blob/develop/.travis.yml spins up a Chutney network on the CI environment for use in integration tests

use Chutney == tor simulation on localhost, it creates for you a mini tor network and you can test integration with Tor there

so you can avoid using the live network

or maybe "PublishServerDescriptor 0" would make them not appear
