Title: Don't force users to match existing config

If an object is in the registry already, and no bespoke config has been
specified - don't consider that an exceptional case.

The scenario which brought me here was having one helper like this:

```
config('assetHost', Configure::read('static.host'));

parent::__construct($View, $config);
}
```

And another like this:

```
An Internal Error Has Occurred
Error: The "Url" alias has already been loaded with the following config: array ( 'assetHost' => '//static.example.dev', ) which differs from array ( )
