Always output upstream if specified

Previously, in running the `manifest` command, we wouldn't output the
upstream if the default upstream would include the pinned sha1.
However, now that fetching refs/heads/* doesn't guarantee that we will
have the sha1, we need to always output the specified upstream branch.
