Fix: task worker num output zero always and enable task worker when defined connections in queue.php

[m3m0r7]

I fixed:

1. Task Worker Num is output zero always when using php artisan swoole:http infos.
   • because $this->config cannot access to queue.php.
2. Did not start task worker (always unset the defined value) when defining connections in queue.php because the laravel-swoole refer queue.default only.

In my use-case, I want to set default SQS (AWS), but another way, I want to use swoole's task worker.
However, the laravel-swoole did not run task worker because the reason is above.
