The cfunc is stored inside the descriptor when doing:
f = Foo()
f.bar() => cfunc is retrieved via tp_descr_get
Foo.bar(f) => cfunc is retrieved via tp_call
Without defining tp_call it will try to call a
wrapping function without the proper flags.

The test is creating a hidden property which can't be accessed
by at the python level => thus the last check is always wrong:
remove it.
