[KrzysztofMadejski]

Issue:

• in \Elasticsearch\Connections\performRequest the line $body = $this->serializer->serialize($body); returns false .. khem khem
• json_encode($data, JSON_PRESERVE_ZERO_FRACTION) return false
• after deleting problematic slug the json was properly encoded

So the real issue is #184
