memory: new `getFilesOwner` method: this method is used by `getFiles` and `setFile` and fill `owner` when it's missing to avoid getting accidentally files from other users. `owner` is not filled in some case (no client, `file_id` or `parent` specified) and an exception is raised if a component has neither `owner` nor `peer_jid` specified.
