Fix i18n wrapper to support CommonJS that was forgotten in d552fde

[xhaggi]

The i18n .wrapper.js was not updated to support CommonJS in d552fde. Without you can't import a translation file in a CommonJS environment.

@mistic100 it would be nice to see this MR merged for the next patch release. At the moment you can't import the i18n files e.g. import 'jQuery-QueryBuilder/dist/i18n/query-builder.de.js';
