There's no real reason to do this as they come out as the same due to Reddit's API limitations, and removing the `None` conversion allows an optimisation in `main.py`.

- Calling comment.body once in main.py and simply passing the body into all these functions significantly reduces the number of calls

- Also improved the typing of some functions
