Code review comment for lp://staging/~brendan-donegan/ubuntu-power-tests/tc-powermeter-07

Max, I don't know if this is what you're looking for, but there is a helper used in the sanity wizard test to remove existing wi-fi connections before the test and restore them after:

It sounds like the implementation would need to be split between the test which removes the connection and prepare-device script which restores it. Could be of use though.
