Update Drupal core to 8.4.7 via Composer. Security update; I *think* we've
been lucky to get away with this so far, as we don't support self-registration
which seems to be used by the so-called "drupalgeddon 2" attack that 8.4.5
was vulnerable to.

             $currentParameters = array();
             if ($query) {
                 parse_str($query, $currentParameters);
             }
 
-            $queryString = http_build_query(array_merge($currentParameters, $this->getValues()), null, '&');
+            $queryString = http_build_query(array_merge($currentParameters, $this->getValues()), '', '&');
 
             $pos = strpos($uri, '?');
             $base = false === $pos ? $uri : substr($uri, 0, $pos);
             $uri = rtrim($base.'?'.$queryString, '?');
         }
