Add scratch-l10n dependency (#1799)

* update scratch-l10n dependency

The new scratch-l10n package includes a script that will push the source file to transfex. Updated the package.json to push the source after extracting strings.

Travis deploy that will build and push strings if run as a cron job

* Fix package-lock

Ran `npm i` as suggested by failing travis log.
