Test::CleanNamespaces 0.06 is busted - we don't even pass our own tests
we need a test requires on Test::CleanNamespaces
Dist-Zilla-Plugin-Test-CleanNamespaces-0.002

          - ensure we depend on a fixed version of Test::CleanNamespaces
          - fix missing prereq caused by us running our generated test in
            tests, where [AutoPrereqs] did not know about it
