FIX: Removes column ambiguity and auto disables incrementing

Removes column ambiguity when using named scopes, an issue that would occur if you are using joins in your query on a table that also contains the uuid field.

```php
$query->where(function ($query) {
    $query->join('tableB', 'tableA.columnA', '=', 'tableB
})->uuid($uuid);
```

Also auto-disables incrementing if the uuid column is set to `id`, which is useful in that developers no longer need to add this property to potentially dozens of Models.
