Add needed facets to faceted search content views

Content views flagged "faceted search" need a few facets to be compliant with the default faceted search in Nuxeo.

• need to add the "FacetedSearch" and "HiddenInNavigation" facets
• remove the "HiddenInFacetedSearch" facet (if any)

See the default reference contribution:

<doctype name="FacetedSearchDefault" extends="FacetedSearch">
  <schema name="faceted_search_default" />
  <facet name="FacetedSearch" />
  <facet name="HiddenInNavigation" />
</doctype>
