housekeeping: reorganize and rewire Mocha tests (#5600)

* move Mocha-run tests to `test/mocha`

* fix relative paths

* fix JSX test paths

* update stagnated JSX tests

* `test/setup.js` -> `test/mocha/setup.js`

* use regex+globstar for test matching

* remove `console.log`

test/mocha/core/plugins/swagger-js/withCredentials.js
