Bug 18624: Regression test for 'any' vs 'all'

Bug 18624: Regression test for 'any' vs 'all'

This test makes it explicit that the only string producing _all as index on build_authorities_query_compat is 'all'.
To test:
- Apply this patch
- Run:
  $ sudo koha-shell kohadev
 k$ cd kohaclone
 k$ prove t/db_dependent/Koha/SearchEngine/Elasticsearch/QueryBuilder.t
=> FAIL: Test fails because the list of valid values is wrong in Koha.

Note: this list has to be in sync with the templates passing the same values. A followup will be added
to fix a discrepancy found between OPAC and Intranet.
