Disable locales on pre-merge Jenkins build in order to save ~25s on builds that require webpack to recompile. This also lets us clean up the code that builds the js-runner image. Pre-merge builds will still verify the i18n tasks in the Linters job, and post-merge builds will continue to build / run all tests using locales.
