HandlesRelationStandardOperations->isOneToOneRelation seems to ignore HasOneThrough

Hi,

I have the following situation:

Model Document --> 1:1 --> Model File --> 1:1 --> Model FileContent.

My model definition of my Document looks like

public function file(): HasOne
{
    return $this->hasOne(File::class);
}

public function filecontent(): HasOneThrough
{
    return $this->hasOneThrough(Filecontent::class, File::class);
}

I declared the following routes (routes/api.php):

• Orion::resource('documents', DocumentController::class)
• Orion::hasOneResource('documents', 'file', FileController::class)
• Orion::hasOneThroughResource('documents', 'filecontent', FilecontentController::class)

These declarations result in the following routes:

| POST      | api/documents/{document}/file
| DELETE    | api/documents/{document}/file/{file?}
| PUT|PATCH | api/documents/{document}/file/{file?}
| GET|HEAD  | api/documents/{document}/file/{file?}
| POST      | api/documents/{document}/filecontent
| DELETE    | api/documents/{document}/filecontent/{filecontent?}
| GET|HEAD  | api/documents/{document}/filecontent/{filecontent?}
| PUT|PATCH | api/documents/{document}/filecontent/{filecontent?}

When I send the PATCH-Request to http://localhost/api/documents/50000/filecontent (where 50000 is the ID of my Document model), I get the following error response:

{
    "message": "Relation key is required, if relation type is not one-to-one",
    "exception": "InvalidArgumentException",
}

Please check, if my fix is okay for you (and save enough :-))
