fetch: download bundles once, even with --all
When fetch.bundleURI is set, 'git fetch' downloads bundles from the given bundle URI before fetching from the specified remote. However, when using non-file remotes, 'git fetch --all' will launch 'git fetch' subprocesses which then read fetch.bundleURI and fetch the bundle list again. We do not expect the bundle list to have new information during these multiple runs, so avoid these extra calls by un-setting fetch.bundleURI in the subprocess arguments. Be careful to skip fetching bundles for the empty bundle string. Fetching bundles from the empty list presents some interesting test failures.
