Correct ExtensiveForm docstring arg order and add missing parameter (…

…#465)

- Update the docstring of the `ExtensiveForm` class to match the order of
  arguments in the `__init__` method signature.
- Add the missing `all_nodenames` argument to the docstring, using a
  description consistent with the parent class `SPBase` but styled to
  match `ExtensiveForm`.
