Error in Buzz/lib/Buzz/Client/FileGetContents.php causes Doctrine/Search/Http/Client/BuzzTest.php to fail

[mikelohmann]

There seems to be an error within the /Buzz/lib/Buzz/Client/FileGetContents.php when executing the Doctrine/Search/Http/Client/BuzzTest.php. Therefor I just commented out the BuzzTest::testCallNotExistingHost-Test to commit my changes.

1. Doctrine\Search\Http\Adapter\Client\BuzzTest::testCallNotExistingHost
   Undefined variable: http_response_header

The test testCallNotExistingHost use the wrong parameters.

I create a pull request.
