Pre-commit: exclude mypy for all tests

[unkcpz]

Not worth to have strict type check by mypy for tests/* .

I am kind of ambivalent about this change, leaving up to @agoscinski.

It was from a thing I learned from Rust. It usually not recommend to use unwrap in the source code but the unwrap is extremely suitable and the right thing for tests. I think it kinds of similar for mypy to python. If the tests fail it fail, and the tests go through the "happy path" of the codes. Type checking will sometime too strict to consider beyond the "happy path". I hope it is not too aggressive.

I think keeping a static type checker still would improve readability, but it also increases the development time. Especially, my experience with mypy is that you can sink in a lot of time until you fixed something that is not even very relevant. Since the tests follow a simpler logic than the src code I would say we can loosen up on readability a bit for the tests a bit to speed up development time.
