Elastica version 3 introduces breaking change

[BrianAltenhofel]

Original issue: https://www.drupal.org/node/2646088

After running a composer update, the Elastica library upgrades to version 3.0 where some search_api_elasticsearch_elastica dependencies have been removed, such as Elastica\Facet\Terms.

The module needs a more specific Elastica version in composer.json.

Thus will have been fixed with the latest merge. :+1:

Since the latest merge, the facet options doesntz work anymore. when clicking one facet, the result ist filtered but the remaining facets are not.
