docs: Unstubs all stubbed methods and functions
  
      If you don't pass in any argument, *all* registered mocks and
      patched modules, classes etc. will be unstubbed.
  
      Note that additionally, the underlying registry will be cleaned.
      After an `unstub` you can't :func:`verify` anymore because all
      interactions will be forgotten.
