query config is required else throws error

The following code snippet generates an error: [TypeError: Cannot call method 'hasOwnProperty' of undefined]

```
orm.connect({database:'ultimet.db', protocol:'sqlite'}, function (err, db) {
   if (err) {
       console.error(err);
    } else {
        console.log('connected to the DB');
    }
});
```

If I include this in the connect() options then it works fine.

```
query:{debug:true}
```
