It appears that wrong component is being passed to the shallow function in this test.
Instead of passing ListComponent into shallow it needs to pass WrapperComponent.

    WrapperComponent = listWrapper(MockListComponent);
    wrapper = shallow(<WrapperComponent />);

In fact you don't even need the ListComponent variable see the changes in my fork.
