DataHandlerHook method findFileByFileReference throw exception if a file reference is marked as hidden

[mediaessenz]

To reproduce:
Add a content element containing a image and add two images, save, set one image to hidden, save again, set second image to hidden and save -> the exception "There is something broken with the File References. Consider updating the Reference Index." will be thrown.

Cause:
The reference(s) are not found, because of there hidden states, which constraint is not removed inside the Fab\Vidi\Service\DataService::getRecord method.

Possible Solution:
Add a third parameter "withHidden = false" to the Fab\Vidi\Service\DataService::getRecord method, and add a remove to this restriction if set:

    /**
     * @param string $tableName
     * @param array $demand
     * @param bool $withHidden
     * @return array
     */
    public function getRecord(string $tableName, array $demand = [], $withHidden = false): array
    {
        /** @var QueryBuilder $queryBuilder */
        $queryBuilder = $this->getQueryBuilder($tableName);

        if ($withHidden) {
            $queryBuilder->getRestrictions()->removeByType(HiddenRestriction::class);
        }

        $queryBuilder
            ->select('*')
            ->from($tableName);

        $this->addDemandConstraints($demand, $queryBuilder);
        $record = $queryBuilder->execute()->fetch();
        return is_array($record)
            ? $record
            : [];
    }

Additional add true as third parameter to the call inside the findFileByFileReference method:

    /**
     * Retrieve the File identifier.
     *
     * @param $fileReferenceIdentifier
     * @return int
     * @throws \Exception
     */
    protected function findFileByFileReference($fileReferenceIdentifier)
    {
        $record = $this->getDataService()->getRecord(
            'sys_file_reference',
            [
                'uid' => $fileReferenceIdentifier
            ],
            true
        );

        if (empty($record)) {
            throw new \Exception('There is something broken with the File References. Consider updating the Reference Index.', 1408619796);
        }

        $fileIdentifier = $record['uid_local'];
        return $fileIdentifier;
    }

Maybe also other places using getRecord should set the third parameter to true, but I can't assess it. In the end its also good to remove the hidden restriction in all cases, because EXT:media operates only in the backend.

[EDIT]
I just realized that the getRecord method is part of EXT:vidi and not EXT:media, which is also used by EXT:vidi_frontend. So removing the hidden restriction at all is maybe not the best solution.
