'use strict' in JavaScript langdb

JSHint can complain about this in build checks, and it shouldn't
hurt anything. But correct me if I'm wrong.
Add autonym to code 'no'
Prevent appearance of redirects in the rendered list

utils.getLanguagesByScriptGroup() runs on the object's languages
property and not on all the langdb languages. This caused
the redirects to be counted as languages. I fixed this,
and added a test to prevent it.

Also update JS langdb, because it went out of sync in of
the previous commits.
