turn off ads from the integrated tests

there is a popup making our integrated tests flaky, maybe these tests should really test without adverts (so we can trust them more) 

Perhaps we also need to rerun the tests (giving a result that we trust less) with ads on - tbd
@kelvin-chappell  the only purpose is to expire and force us to decide whether to leave ads off or on for the test.  but I don't think I can use the actual switches from the tests, unless you know different?
