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.
