Aggregator.models wasn't passing the value for filter_downloaded through to the models method of the Repository subclass. This means that by default the subclass's models method always fired with filter_downloaded=True, which meant that if there were no models already downloaded, calling bergamot download didn't download anything as it couldn't discover the undownloaded models. This PR fixes this behaviour.
