Deleting Model does not deletes directory in custom path generator.

[Jagdish-J-P]

We have used custom path for media storage. Our structure is as below:

'medias/' . $media-> model_id . '/' . $media->id . '/'

When we use $model->deleteMedia() it does not deletes directory under medias i.e. model->id is not deleting only children are deleted.
