i believe the issues surfaces in this are fixed at this point.

of note, my mock_call_test.py example now passes.

i'm not entirely sure that it _should_ pass though, but that depends on what we want create_autospec of a class to do.  should that autospec'd class require instantiation before methods are called?  _that_ is outside the scope of this issue.  As is, the current behavior is likely what people expect to find convenient.
