[createClientFactory] Trying to connect to localhost when using createClientFactory

Kue is trying to make a connect to localhost after I have successfully connected to a non-localhost redis server.

```
events.js:141
throw er; // Unhandled 'error' event
^

Error: Redis connection to 127.0.0.1:6379 failed - connect ECONNREFUSED 127.0.0.1:6379
at Object.exports._errnoException (util.js:870:11)
at exports._exceptionWithHostPort (util.js:893:20)
at TCPConnectWrap.afterConnect [as oncomplete] (net.js:1063:14)
```

This happens after I successfully connect to my redis server (which does not sit on localhost).

My dependencies:

```
├── kue@0.10.5
├── kue-ui@0.1.0
├── redis@2.6.0-1
```

I am using node-redis has my redisClient:

```

app.redisClient = redis.createClient(config.redis.port, config.redis.host);
app.jobs = kue.createQueue({
redis: {
createClientFactory: function () {
return app.redisClient;
}
},
disableSearch: true
});
```

Is Kue trying to make another connection for another feature that I am not across?

Cheers,
Peter

Start at the kue.createQueue redis option and trace how createClientFactory uses the redis.createClient instance when connecting to a non-localhost server. Reproduce the supplied configuration and confirm that creating the queue does not attempt an additional connection to 127.0.0.1:6379.
