NIHVIVO-3357 - updated autocomplete generator and autocomplete template: generator returns empty list in case only owl:Thing returned, as Solr search doesn't create the index using this class, and updated freemarker template so that the type parameter for autocomplete is only passed in case the types list from the generator is not empty. Also added similar logic for parameter value for "multiple types"
