Fix second params of findOneBy in file Abstract

[angie-laurenti]

When I generate DAOs, in files like Abstract (no editable), DAO can generate function findOneBy .. like this for example in AbstractDocumentTypeDao :

    /**
     * Get a DocumentType filtered by whiteLabel, documentModels.
     *
     * @param WhiteLabel $whiteLabel
     * @param DocumentModel $documentModels
     * @param string[] $additionalTablesFetch A list of additional tables to fetch (for performance improvement)
     * @return DocumentType|null
     */
    public function findOneByWhiteLabelAndDocumentModels(WhiteLabel $whiteLabel, ?DocumentModel $documentModels = null, array $additionalTablesFetch = array()) : ?DocumentType
    {
        $filter = [
            'white_label_id' => $whiteLabel->getId(),
            'document_models_id' => ($documentModels !== null) ? $documentModels->getId() : null,
        ];
        return $this->findOne($filter, [], $additionalTablesFetch);
    }

In my schema DB, white_label_id and document_models_id are NOT NULL

So, second params should not be an optional parameter.

Can it be corrected? Thank you
