Title: [HttpFoundation] Removed useless check if self::$trustProxies is set

In Request::getClientIps() on line 772 there is a check if self::$trustedProxies is not set. If this condition evaluates to true the method will return.
Because of this, the second identical check on line 783 will never evaluate to true.
