EntityResourceTestBase.php uses a static query that should be dynamic

The file EntityResourceTestBase.php uses a static query.

$cache_items = $this->container->get('database')
      ->query("SELECT cid, data FROM {cache_dynamic_page_cache} WHERE cid LIKE :pattern", [
        ':pattern' => '%[route]=rest.%',
      ])
      ->fetchAllAssoc('cid');

SQL Server uses square brackets as an escape character in LIKE clauses. The following would be equivalent, yet allow contrib database drivers to alter the query as needed.

$cache_items = $this->container->get('database')
      ->select('cache_dynamic_page_cache', 'c')
      ->fields('c', ['cid', 'data'])
      ->condition('c.cid', '%[route]=rest.%', 'LIKE')
      ->execute()
      ->fetchAllAssoc('cid');
