Improve prestart and tests (#1610)

* screenshotter: replace promisify(fs) and mkdirp with fs-extra

* screenshotter: replace selenium.promise with builtin Promise

* Lint all JavaScript files in the root

* unicodeMake: replace console.log with writeFile(string)

* unicodeMake: check timestamp, do not build if up-to-date

* Replace check-dependencies with yarn check

* Exclude src/unicodeMake.js from coverage

* Add (missing) dependencies

* Skip CircleCI if only unrelated has been changed

* Fix commit range

* Use fs-extra in update-sri
