More than one group breaks permission tab in Drupal 9.2.0

Problem/Motivation

The group permissions tab is crashing if more than one group is available

Steps to reproduce

• 1. Install group_permissions in Drupal 9.2.0
• 2. Create a group type
• 3. Create a new group -> group permissions tab work well
• 4. Create a second group -> group permissions tabs crashed

An Error ist thrown in the validate funtion of the UniqueReferenceFieldValidator.php

/modules/contrib/group_permissions/src/Plugin/Validation/Constraint/UniqueReferenceFieldValidator.php

Proposed resolution

The problem seems the query inside the validate function (maybe there are parameters missing). Change the SQL-query so the function validates correctly
