test: split tests of various validators

[WikiRik]

This PR splits tests for 15 validators from the big file to individual files. All of these validators should not have open PRs that would need rebasing after merging this. Organization members can look at this project to see which PR affects which validator.

Additional PRs with the same goal will follow in the future but I'm starting with this to make the review process relatively easy.

Checklist

• PR contains only changes related; no stray files, etc.
• README updated (where applicable)
• Tests written (where applicable)

I'd prefer that you split out the huge ones that keep changing often first, e.g. isMobilePhone. Huge here is any validator perhaps with >100 locs?

[WikiRik]

For isMobilePhone specifically; when I made this PR there were about 50 open PRs for that. So I thought that would cause too many merge conflicts. But once we go through those and the open PRs left are outdated or merged I can work on splitting isMobilePhone away.

But I will see about other large validators soon, thanks for the comment!
