test suite fails with recent MiniTest and TestUnit

[voxik]

It seems that assert does not accept object as a test message anymore. #to_s could be used to fix this issues, however I am not sure that it will improve the readability in case of failure.

Test-Unit:

I cleaned up the tests in this commit: https://github.com/mmell/ruby-openid/commit/9c112b067ee05f579bc6a9288e5bb3105af563a7#test

If you pull my branch, I think the tests will work for you.
