Fix issue with route scope binding when getRouteKeyName method is different from Route scoped

[Joemires]

There's a problem when you are using

Route::apiResource('products', Controllers\Store\ProductController::class)->scoped(['product' => 'slug'])

The documentation still uses your getRouteKeyName model method and this is a great problem for people with special routes having their special scopes

I probably only know about 30% of Laravel features at this point. 😅

Please fix the tests + add a new one for this use case, if possible.

[shalvah]

Tests fixed (wasn't your fault), but can you add a test for this too?

Hey @shalvah
Sorry I was busy with things

I'll look into this and revert
