should_not allow_mass_assignment_of fails when all attributes are protected.

[cgriego]

I ran into this bug with Rails 3. I have a model where I used attr_accessible without a list of attributes to make all attributes protected. But because my white list is empty, AllowMassAssignmentOfMatcher fails to realize the model is using whitelisting so RSpec ends up throwing exceptions. The #whitelisting? check should not rely on there being an attribute white-listed.

Workaround: Make up a fake attribute. Ugly, but works.

Looks like this is fixed in the latest version of shoulda (see here), so I"m closing. Feel free to re-open if I'm wrong.
