When creating a call chain with a mocked function jest.fn() that has arguments, you should be able to call that function and recieve the return value as written.

Currently, when building the mock models, the mocked function is correctly qualified as a function but is then returned as part of another jest.fn().mockImplementation(...) call, which causes unexpected return values based on the originally specified mock.

Passing an explicit value of undefined causes the below error to be thrown, preventing the package from returning a mocked model list.

Cannot destructure property 'toObject' of clone(...) as it is undefined

Intemediary call chain steps (populate in find.populate.exec) cannot be asserted on.

This is due to the mapCallSteps function directly returning intemediary steps instead of converting them into mocked functions as they are reduced.
