Testable?

> Testable?
Not really, as the tests are always either `"page"` or `"web-page"` (or don't use `InspectorBackend` at all) and therefore already had all of the domains that had enums.  We maybe could do something like checking that a WK1 test has `InspectorBackend.Enum.Target.TargetInfoType` (since that's only enabled for `"web-page"`, but that seems kinda awful :/

Oh wait no I'm completely crazy yes we can add a test.  Just check for `InspectorBackend.Enum.ServiceWorker` (even though there are no enums in `ServiceWorker`) :)
