Now preview state can be one of (allowed, cancelled, empty-in-edit). In case of editing a message without preview we set the state to empty-in-edit and it changes to allowed if the links in the message are changed somehow. That way we don't need to cancel the preview when editing a message with a cancelled preview and at the same time adding a link to a message that had no preview in the first place will add a preview.
