Temporarily removed test due to active-fedora 6.6 incompatibility issue
Changed :class_name to 'ActiveFedora::Base' for compatibility with active-fedora 6.4.4+
which effectively requires the :class_name argument to refer to an ActiveFedora model
(ActiveFedora::Base or subclass) and not a module.
See https://github.com/projecthydra/active_fedora/commit/8ac538eb4442bde23e561735e00d28ff50d55744.
