Fix for ff4j elasticstore

ElasticQueryBuilder

public Search queryReadAllFeatures(Integer totalCount) {
  return new Search.Builder(new SearchSourceBuilder().size(totalCount).toString()).addIndex(connection.getIndexName())
      .addType(ElasticConstants.TYPE_FEATURE).build();
}

FeatureStoreElastic.java

@Override
public Map<String, Feature> readAll() {
    SearchResult resultTotal = getConnection().search(getBuilder().queryReadAllFeatures(), true);
    Map<String, Feature> mapOfFeatures = new HashMap<String, Feature>();
    if (null != resultTotal && resultTotal.isSucceeded()) {
        Integer total = resultTotal.getTotal();
        SearchResult result = getConnection().search(getBuilder().queryReadAllFeatures(total), true);
        if (null != result && result.isSucceeded()) {
            for (Hit<Feature, Void> feature : result.getHits(Feature.class)) {
                mapOfFeatures.put(feature.source.getUid(), feature.source);
            }
        }
    }
    return mapOfFeatures;
