location header not set in response when calling filter from controller

[leberknecht]

According to the readme, the following code should return the browser path for the generated thumb if called from a controller:

$imagemanagerResponse = $this->container->get('liip_imagine.controller')->filterAction(
[...]
);
$srcPath = $imagemanagerResponse->headers->get('location');

With Sf 2.2.2dev and liip/imagine-bundle:dev-master, the location field is not set in the headers.

Well, the README is wrong on this and will be updated.

Very interesting by the answer as well. Thx to update the README or just explain the solution.

@michmichant check #175, it's about CacheManager::getBrowserPath.
