update circuit browser to use uniqueFacets

[Robbie1977]

@jrmartin can you change the code for the circuit browser to use 'uniqueFacets' rather than 'labels' for the coloured labels/key in the neo4j/pdb query results.

    }
  },

FYI no changes are needed to the solr code for Circuit Browser as we are still using the full labels list for filtering.
