Changed facet navigation view not updated in Channel Manager

Components using facet navigation to show their content are not updated when the facet navigation view is changed, e.g. by an underlying content change.

Case:

• a banner component relying on a facet navigation view, filtering out banners with a property set to "archived" 
• if a banner is changed to be archived, this is reflected in the live site but not in the Channel Manager preview

The reason is that there's a JCR session bound to the HTTP (CMS) session, and it's is not refreshed, hence the virtual view of facet navigation results are not updated.

 Possible fix: add a session.refresh or session.localRefresh in the CmsSecurityValve
