Switch to the Docker-based infrastructure on Travis

Same than minkphp/MinkSelenium2Driver#210

hmm, weird. Why would we get errors in the fixtures for some jobs and not others while they all run them with the PHP 5.6 webserver ?

Looks like I may need another solution

Solution is perfect. What creates a problem is Guzzle. If you have Guzzle 5.x or smaller installed, then with your setup (PHP 5.6 as a web server and PHP 5.5 running the tests) all works.

If the Guzzle 6.0.1 (or I guess any 6.x version) is used the cookie related tests start to fail.

I've seen issue/PR recently where somebody attempted to fix something Guzzle 6.x related, but I'm not sure if it was merged to Guzzle/GoutteDriver or it was related.

Can't seem to figure out at which step it fails. When driver is asked for tc cookie value the value is there, but when $_COOKIE['tc'] is called in issue140.php the $_COOKIE array is empty. Seems that Goutte 6.x doesn't properly send Set-Cookie headers back on page redirects (just a guess).

@aik099 there is a bug in Goutte 3 when using custom ports in the URL. See FriendsOfPHP/Goutte#236 for the fix.

here we go. The Goutte bugfix has been merged.
