The request generator applies the default skin layer to the request.
We have a specially crafted request that tests this. If the
request does not have the required interface it raises an
ValueError. Let's see that this works as expected

>>> setDefaultSkin(request)

Retries generate new request objects, the publisher needs to
ensure that the skin layer is applied to those as well. If the
skin layer is not applied to subsequent requests, an ValueError
would be raised here.
