Fixed ElasticSearch 6.8.x deprecation warning spam due to XF searches

Affected version
Using XF2.1.4 and ElasticSearch 6.8.10, the elasticsearch_deprecation.log log file is repeatedly being spammed with this for every search;

[2020-07-16T12:21:11,512][WARN ][o.e.d.s.f.s.DocValueFieldsFetchSubPhase] [node01] There are doc-value fields which are not using a format. The output will change in 7.0 when doc value fields get formatted based on mappings by default. It is recommended to pass [format=use_field_mapping] with a doc value field in order to opt in for the future behaviour and ease the migration to 7.0: [discussion_id, user, date]
