Create the url_cache index on local_media_repository as a background update, so that we can detect whether we are on sqlite or not and create a partial or complete index accordingly. To avoid running the cleanup job before we have built the index, add a bailout which will defer the cleanup if the bg updates are still running. Fixes https://github.com/matrix-org/synapse/issues/2572.
