Not working on symfony 3

[gawrrell]

I've recently updated from symfony2 to symfony3 and I get this error on cache:clear command:

....vendor\ticketpark\barcode-bundle\Ticketpark\BarcodeBundle\DependencyInjection/../Resou
rces/config\services.yml" does not contain valid YAML.

[Symfony\Component\Yaml\Exception\ParseException]
The reserved indicator "@" cannot start a plain scalar; you need to quote the scalar at line 9 (near "arguments: [@
ticketpark.file.handler]").

[gawrrell]

I think I've found a solution:
I've put all @ references inside double quotes, ex:
arguments: ["@ticketpark.file.handler"]

Yes, this is necessary in Symfony 3. Would you care creating a pull request with the changes?
