Test failures with python 3.11+

[shish]

I'm using TestSlide version: f22c183

Given: no changes

When I run: make

I expected this to happen: tests pass

But, instead this happened:

  1) mock_constructor(), patching mechanism, original class attribute access: can call class methods
    1) TypeError: Target.regular_class_method() missing 1 required positional argument: 'cls'
