Add missing js translations to openedx

Client-side translations are stored in "djangojs.js" files. Supposedly,
these files were properly compiled prior to the Ironwood release -- but
this is not the case, so we need to re-generate them.

Also, we need to re-generate the djangojs.js files for the custom,
downloaded locales. The assets collection settings are also fixed to
take into account the separate locale folder.

This step needs to happen prior to static assets collection, as the
djangojs files are collected to the staticfiles/ folder.
