Errors on user overview page when user can edit all roles

Hi,

If I have a role that is allowed to edit all other roles I'm seeing this error:

Drupal\Core\Database\DatabaseExceptionWrapper: Exception in People (administerusersbyrole)[administerusersbyrole_people]: SQLSTATE[42000]: Syntax error or access violation: 1064 You have an error in your SQL syntax; check
               the manual that corresponds to your MySQL server version for the right syntax to use near ')
               WHERE (( (users_field_data.default_langcode = '1') AND (users_field_data.uid !' at line 2: SELECT COUNT(*) AS expression
               FROM
               (SELECT 1 AS expression
               FROM
               {users_field_data} users_field_data
               INNER JOIN {user__roles} ur ON ur.entity_id=users_field_data.uid
               LEFT OUTER JOIN {user__roles} ur_2 ON ur.entity_id=users_field_data.uid AND ur.roles_target_id IN ()
               WHERE (( (users_field_data.default_langcode = :db_condition_placeholder_0) AND (users_field_data.uid != :db_condition_placeholder_1) ))AND (users_field_data.uid  :db_condition_placeholder_2) AND (ur_2.entity_id IS NULL )
               ) subquery; Array
               (
                   [:db_condition_placeholder_0] => 1
                   [:db_condition_placeholder_1] => 0
                   [:db_condition_placeholder_2] => 1
               )
                in Drupal\views\Plugin\views\query\Sql->execute() (line 1488 of /var/www/sites/smg/smg3/docroot/core/modules/views/src/Plugin/views/query/Sql.php).

If I exclude one role, the error goes away.

In administerusersbyrole_query_administerusersbyrole_edit_access_alter(), because there is nothing in $exclude, the query isn't valid.

If I add

    if (!$exclude){
      return;
    }

at line 132, there's no error and the user list looks fine. (or I could wrap the last part in if($exclude)).

I don't know enough about the module to know if that's correct in all situations.

thanks.
