The yet-to-be introduced client support for bundle-uri will always fall back on a full clone, but we'd still like to be able to ignore a server's bundle-uri advertisement entirely.
This is useful for testing, and if a server is pointing to bad bundles, they take a while to time out etc.
Since we might see the config in any order we need to clear out any accumulated bundle_uri list when we see transfer.bundleURI=false setting, and not add any more things to the list.
