Instance Exception when referenced Resource extends Laravel\Nova\Resource and not App\Nova\Resource

[stiknoltz]

First off thanks for creating this library. I've found it very useful.

I did notice the following which can occur in certain instances where you're including other Nova Resource generating Packages.

There is a type hint on line 48 of src/Http/Controllers/ImportController.php for an App\Nova\Resource class which fails if the Resource is from another vendor package which generally reference Laravel\Nova\Resource and not one created locally.

Since Laravel\Nova\Resource as NovaResource is already imported, the fix was was just a matter of changing the Resource type hint to NovaResource

I think #7 might be related to this issue.

Wasn't sure of the best way to provide this, but here's a diff of the proposed solution:

             return [$resource->uriKey() => $resource->creationFields($request)];
         });```

@stiknoltz I've just released this fix. Could you update your version and let me know if it's working for you?
