[BUG] LPL throwing an error

[Sevhena]

Here is the smell I attempted to refactor:

Maybe the **kwargs was the issue?

this is the error:

Traceback (most recent call last):

I'd strongly suggest you install the Pylance vscode extension if you haven't already. For me your code looks like this:

While the above error cannot be reproduced since LPL Refactorer switched to libcst, the case for variadic keyword and positional args using *args and **kwargs was still unhandled by the refactorer. Refactorer now handles this, and unit tests have been added.
