Implemented patch for views with duplicate nodes

Views relationships with multi-valued entity reference fields invalidate Distinct query option

(https://www.drupal.org/project/drupal/issues/2993688)

This is an issue with a lot of views in the installation which make use of entity relationships. Using the module views_distinct often results in wrong numbering in the pager which results in empty spaces in a multi-page view. This patch is a first solution for it but need further observation.

Implemented 8th of March 2022
