The new Elasticsearch Java client did not keep null values when writing the data to Elasticsearch (the old client did). As Spring Data Elasticsearch only adds null valued fields that are explicitly marked to be stored this way this change broke the expected behaviour.
This PR changes the configuration of the object mapper used by the Elasticsearch client to write null values.
Closes #2839
