ExchangeDeclaredException commented because prevents several channels usage

Q	A
Is bugfix?	✔️

I'm trying to use several channels pushing messages this way

use Yiisoft\Queue as YiiQueue;

class Queue
{
    public static function get(string $channel = YiiQueue\QueueInterface::DEFAULT_CHANNEL): YiiQueue\QueueInterface
    {
        $di = DI\ServiceLocator::getInstance();

        $adapter = $di->get(YiiQueue\Adapter\AdapterInterface::class)
            ->withChannel($channel);
        $queue = $di->get(YiiQueue\Queue::class);

        return $queue->withAdapter($adapter);
    }
}

Queue::get('{custom-channel-name}')->push(/* message */);

Everything is ok here, message successufully pushed to new queue of RabbitMQ.

But when trying to use build-in commands, like listen {custom-channel-name} get ExchangeDeclaredException().
As I discovered while researching the source code problem occurs on line 84 of src/QueueProvider.php because $this->exchangeSettings never equals to null because of default value in __construct().

Used this as hard-fix only
