array_shift($value) will work on an array with non integer hash keys.
question remains why the key is "***LANGUAGE_language_interface***" and not 0?

Did anyone double check if it works with the database backend?

@mkalkbrenner, just tested it with the db backend and it's working fine. The issue is only related to the SearchApiSolrBackend when only one value is selected.

I created a test only patch on top of #2775497: Run \Drupal\search_api\Tests\ViewsTest on Solr Backend.

But this test succeeds! Can you tell me some more details about your setup?

It's a search_api_solr view.

PHP 7 (tested with php 5.6 that's not the issue), Drupal 8.1.7 with Solr 6 and 2 languages enabled.
Created an index with some node types and some fields among which language.
Created a search view that shows rendered entities on this index with a filter Item language: The item's language.

I still can't reproduce the issue, in other words I always get numeric index keys.
Nevertheless the patch makes sense as it is more robust, even for future usages.
But we if we do the array_ahift(), we have to it for the other operators as well, not just for one particular operator.
I attached an enhanced patch.
