Fix moment import inconsistency

On the first hand, at build time, we vulcanize moment-import.html which has a relative path to moment.js library which is not adapted during gulp build time and which results in:

nuxeo-app.html:64646 GET https://nightly.nuxeo.com/nuxeo/moment/moment.js net::ERR_ABORTED 404

On the other hand, in index.jsp we actually need moment-with-locales.min.js.
