Code review comment for lp:~brendan-donegan/ubuntu-clock-app/disable_location_prompt

Also, it feels wrong to use sudo during the test. Another ugly workaround we have to use because the location-service and the trust prompt where not consulted with QA, and there is no good test strategy around them. My suggestion is to involve jfunk and thomi in the discussion, so they put pressure on the devs to give this problem a high priority. Depending on what they say, it would be easier to decide if we should apply this workaround or wait for a proper fix.
