test: run tests shuffled

[Shinigami92]

closes #1318

Waiting on merge of:

• test: fix system fileExt assumption #1646
• test: fix duplicate test names #1647
• feat(number): adjust hex default #1649

This PR configured vitest to run the tests in shuffled mode

While this seems to solve the issue of testing always with the same values, it also renders our random seeded tests useless, because the tests are no longer reproducible (by setting the previous/failing seed) in case they uncover a test failure.

I assume this still is likely to use seeds values close to our seeded tests (fixed seed + 1 or 2 calls).

Uh damn it, I accidentally pushed it directly to this PR 🤷
I wanted to extract it to its own PR, but nevermind anyway.
The new commit fixes the mersenne test and additionally removed a todo from a test so it actually gets executed.
