Better default for queue driver

[FoxxMD]

Should we attempt to find the default queue driver specified in Laravel's /config/queue.php? Or throw an exception and force the user to explicitly set it?

Hi, just stumbled upon your package, it really gave me a good starting point for my own solution.

I updated some configuration to be compatible with Laravel 5.7 (env('QUEUE_CONNECTION') instead of env('QUEUE_DRIVER')) and used config('queue.default') to parse the default queue driver. Be happy to send you pull request for the changes, if you are interested.

Let me know your thoughts on this approach, and once again, thanks for this package! 👍

Glad it helped! I'm happy to accept PRs as long as it doesn't break current functionality.

please update the QUE_DRIVER with QUEUE_CONNECTION
