Change I02fb4b445 added the include_type_name parameter on all requests
to Elasticsearch V6, but it turns out that the parameter is not
recognized on earlier V6 versions (e.g. 6.6.* and 6.5.*) and causes
index creation to fail with "bad request".
Fix the query adapter to only put the parameter on requests for version
6.7 and later minor ones.
