* Stop setting a shortcode to newly-created media attachments The WebUI has stopped using the “short media URL” in ages. This isn't used anywhere except for mail notifications. Deprecating it would allow us to eventually get rid of at least a database column and corruption-prone index, as well as a controller. * Fix tests
