Quota - Fix quota js loading

Using a 7.4 snapshot from sept 24

• Set up a postgresql db
• Install the quota add-on
• Compute the initial statistics

• Go to the quota tab in a workspace
  => JS error: ReferenceError: displayQuotaStats is not defined

• Go to the quota / activate tab in a workspace
  => JS error: TypeError: jQuery(...).slider is not a function

Note that looking at the network console:

• Jquery is loaded properly
• The following URL returns a 404 error: http://localhost:8080/nuxeo/wro/api/v1/resource/bundle/nuxeo_includes.css?flavor=default

On the other hand, the quota tab in the admin center displays statistics properly.
