Fix fputcsv annotation

[Jean85]

During #316 I restricted the type of the $field argument, and that triggered my static analysis tools while importing the fix.

As shown in https://3v4l.org/ahdmn, the original fputcsv function will try to cast everything to string, so every scalar is safe, array are risky (they become Array), objects explode, with the exception of stringable ones.

This looks good. The CI error seems to come from a cache error (I had the same on another PR) so I think we can safely merge it. How sure are you of your fix?

[Jean85]

Umh, the PR seems kinda messed up, because the fix was already merged in #316...
Maybe you erased that with your forced push?

[Kharhamel]

What you mean? Which force push? I only ever force-push to my own branches, never to master.

I also fixed the cache, which should solve your CI error. You just need to pull master to benefit from the change.
Also could you squash all of your commits into a single one? That would look cleaner

[Jean85]

GitHub doesn't agree... That's what I see:

You force-pushed, erasing 6b3abbe which was @dbrekelmans merging my #316 into master.

That's why this PR is messy: it's #316 + https://github.com/thecodingmachine/safe/pull/318/files/9f63c60d5f1e746873629fd5447e6b80f7622770..246d93cd3a7d52d7beb33028918d64de45a24329

[Kharhamel]

That's weird. How did I do that. If it is really messed up, the easy way to fix is to simply destroy the commits (but not the changes), stash the changes, start over from a clean master branch and commit. So something like this:

git reset _hashOfTheCommitBeforeYourChanges_
git stash
git checkout master
git pull master
git checkout -b _newBranch_
git stash pop
git commit

If you need help, we can try to meet on discord and fix it together

[Jean85]

Done!
