[BUG] can't SIGINT when using library

[victorperin]

Seems to relate with this bug here:
jprichardson/node-death#7

After SIGINT, I aways get this error:

IllegalOperationError: Channel closed
     at Channel.<anonymous (/usr/src/app/node_modules/amqplib/lib/channel.js:149:11)
     at Channel.C.reject (/usr/src/app/node_modules/amqplib/lib/channel_model.js:244:8)
     at Timeout.msg.reject [as _onTimeout] (/usr/src/app/node_modules/@autolotto/bunnyhop/build/lib/engines/default.engine.js:208:18)

I think we can use this package as alternative:

I think this comment on node-death is a good way to start.

Try this:

const onDeathCallback = () => {
    try {
        shutdownRedis();
        logInfo('Redis');
        shutdownMongoose();
        logInfo('Mongo');
    } catch (err) {
        logError('death.config.onDeathCallback', 'ERR_GRACEFUL_CONN_SHUTDOWN', err);
    }
};
