Empty Index and FacetManagerImpl.getFacets() NullPointerException
-----------------------------------------------------------------

                 Key: HSEARCH-745
                 URL: http://opensource.atlassian.com/projects/hibernate/browse/HSEARCH-745
             Project: Hibernate Search
          Issue Type: Bug
          Components: engine
    Affects Versions: 3.4.0.Final
         Environment: Hibernate 3.6.4.Final, H2
            Reporter: Mike Pugmire


When an index is empty and an attempt is made to retrieve a facet with  facetManager.getFacets(facetingName) a NullPointerException is thrown as facetResults is null when facetResult.get( facetingName ) is called on line 112.

{code}
java.lang.NullPointerException
	at org.hibernate.search.query.engine.impl.FacetManagerImpl.getFacets(FacetManagerImpl.java:112)
{code} 

I'm guessing an empty List<Facet> is an appropriate return value for this situation?
