Force dropdown list update when using Saved Search Page Provider with Elasticsearch

Steps to reproduce :

1. Add "SAVED_SEARCHES_ALL_PAGE_PROVIDER" page provider to the "elasticsearch.override.pageproviders" parameter of the "nuxeo.conf" file.
2. In the WebUI set some search parameters in the Nuxeo default search then save them as a predefined search.
3. Click on the "filters" dropdown menu.

Observed behaviour :

• The predefined search name you just saved isn't listed in the dropdown menu.
• You need to reload the page in the browser to see your new predefined search appear.

Expected behaviour :

• You see the name of the search you saved like before we override the Page Provider in ElasticSearch.
• Refresh of the menu is live after an action and represent the actual state.
