Symfony version(s) affected: 4.3.0

Description
Curl http client try to parse Location header even if no redirects allowed, which makes unable to get response/headers value from endpoint which returns invalid url in Location header.

How to reproduce

use Symfony\Component\HttpClient\CurlHttpClient;

// uses the cURL PHP extension
$httpClient = new CurlHttpClient();
$response = $httpClient->request('HEAD', 'http://test.mleczko.waw.pl', ['max_redirects' => 0]);

Results in InvalidArgumentException Malformed URL ..., no way to use value of this header.

Possible Solution
Simply check if we are gonna use Location value as redirect target - https://github.com/mleczakm/symfony/commit/5c27013e6b1c8f710821019f1ec64fc29f034d3b
