By trajar:

the changes in how the new session hash operations meant that the session id was never really null, since we were mocking the servlet api. so i commented this out - i meant to include a lengthy comment/explanation but i apparently forgot.

i have since looked over the code some more, and updated the spec to all for a null session id, which accomplishes this spirit of this unit test. see follow on commit.
