Gate problematic mock object test (WOTest, 2088ff0)

The handling of unrecognized selectors appears to have changed in Leopard in ways that cause one of the mock object tests to fail. Specifically, an NSInvalidArgumentException is raised and it appears that the -[NSProxy doesNotRecognizeSelector:] method is being called; setting breakpoints indicates that the -forward:: method on the WOMock class is no longer being invoked.

So I am temporarily gating off this test so that we can get error-free test runs, pending further investigation. I plan to rework much of the mock/stub API in any case based on better understanding obtained through my experiences with RSpec (my use of the terms "mock" and "stub" is incorrect, based on my first contact with those terms in the OCMock framework); at a minimum, I plan to rename WOStub and its subclasses to better reflect what it actually does (it is a message recorder and should probably be called as such). I may also later add WOMock subclasses that really are stubs (non-verifying mocks).
