Code review comment for ~cjwatson/launchpad:distribution-information-type

LGTM - I am not super happy about using yet another test-addon, `testscenarios` for all the already mentioned reasons. Additionally skipping tests from within instead of using a decorator was unfamiliar to me. But it works :-) And I lack an immediate better solution.

The last meaningful contribution to this package was 7 years ago, but I saw you are listed as one the maintainers, so I think this is ok.
