Code review comment for lp:~mvo/snappy/snappy-review-tools-reenable

We have an integration test that builds a snap: http://bazaar.launchpad.net/~snappy-dev/snappy/snappy/view/head:/_integration-tests/tests/build_test.go#L49
The build is done in the snappy machine, and it is not expecting the warning we get when click-review is not installed. So, the test needs to be updated to match a more relaxed rexexp. And we need a new card to test more builds including the review, but that should probably wait until comfy is properly defined.
