REST API: Improve test coverage of single users endpoint for public author data

[rachelbaker]

Add test coverage for requests of a single User resource for authors of different post types. Including authors of post types registered as:

• public = true, show_in_rest = true success without auth
• public = true, show_in_rest = false fail without auth
• public = false, show_in_rest = true success without auth
• public = false, show_in_rest = false fail without auth

See #38878

@jnylen0 I know you were working on this, can you pick-up this ticket?

Test all the things

This should be good to go now. One of the older tests was failing during full test suite runs because of some missing self::delete_user calls in other tests, causing one of the tested users to be on the second page of results.

Moving to 4.7.2 - I'd like to get these tests in before we start ​work on multisite users.

Since these are just tests, adding them to 4.7.x isn't a big issue, but also pointless as they'll not actually be "deployed" anywhere, and as you're targeting 4.8+ for the development effort, doesn't it make sense to just add new tests to trunk? It's far less work for everyone involved.

Right, that makes more sense than whatever I was thinking, thanks.
