Subject: [PATCH] Bug 25864: Lower case fields for searching

To recreate:
 1 - Have Koha using ES5 and Elasticsearch as search engine
 2 - Enable DumpTemplateVarsIntranet and DumpSearchQueryTemplate
 3 - Do a search in authorities using 'Search entire record' (abduction if using sample db)
 4 - Note no results
 5 - View the page source and find 'search_query'
 6 - Note the uppercased fields
 7 - curl 'es:9200/koha_kohadev_authorities/data/417?pretty'
 8 - Note all fields lower-cased
 9 - Apply patch
10 - Repeat search
11 - It works!
