Setter is not actually a setter

[jkujawski]

Currently setUserAgent is not actually a setter, because it just returns userAgent.

/**
     * Set the user agent.
     *
     * @param string $userAgent
     */
    public function setUserAgent($userAgent)
    {
        if (is_null($userAgent)) {
            foreach ($this->getUaHttpHeaders() as $altHeader) {
                if (isset($this->httpHeaders[$altHeader])) {
                    $userAgent .= $this->httpHeaders[$altHeader].' ';
                }
            }
        }
        return $userAgent;
    }

Shouldn't it set $this->userAgent ?

Yes, I can see where you are coming from.

Would you like to suggest an improvement via PR?

Thanks 👍
