Reconnection does not stop

[safer-bwd]

If the amqp server is unavailable, the reconnect timer does not stop when the broker stops:

const { ServiceBroker } = require('moleculer');
const AMQPMixin = require('moleculer-amqp');

const broker = new ServiceBroker({ logger: true });

broker.createService({
    mixins: [
        AMQPMixin('amqp://localhost')
    ]
});

(async () => {
    await broker.start();
    await broker.stop();
})();
