Title: Make Redis connection parameters fall back to their default values.

The `createClient` method has been slightly changed in `node_redis@0.12.x`.
It no longer works when used like this: `redis.createClient(undefined, undefined, options);`

This ensures that default values are used when the connection parameters (`port` and/or `host`) are not specified.
