TYPO3 Core

I think the right solution here is to add `getOriginalFile` to the ResourceInterface and File class. On File class this can simply return self.

Essentially: the method signature was changed for a very good reason (PHP7 compatibility) and requiring interfaces is more consistent than requiring either of the specific classes (not least due to the PHP7 signature issue). Whereas the fact that we call a method that is not declared on the interface is bad in and of itself, and fixing that also fixes this issue.

My workaround for this is:

            $file = $targetFolder->addUploadedFile($_FILES['file'], DuplicationBehavior::RENAME);
            $fileResourceReference = new \TYPO3\CMS\Core\Resource\FileReference(array('uid_local' => $file->getUid()));

            /**
             * @var $fileReference FileReference
             */
            $fileSysReference = $this->objectManager->get(FileReference::class);
            $fileSysReference->setOriginalResource($fileResourceReference);

Thank you Timi Kiefer for your comment, it saved me so many hours and I already spent a day for it. Before I did the file reference using setFile (own FileReference Model) but then I was not able to do a $file->getOriginalResource()->getPublicUrl() (missing uid) for just uploaded files in the current action. Now it works! :)
