marvin_refactor: Working around CLOUDSTACK-2126

Marvin deserializes by matching attributes of the response with the
responseObject expected. In case the object's attributes don't mirror
the response Marvin assumes the response is invalid and can't return a
proper first class entity. This makes it difficult for tests to
reference the object's attributes in a sensible way.
