fix(vcs-downloader): abort on local changes in parent cleanChanges path

The VcsDownloaderBase::clean_changes stub returned Ok(None), silently
swallowing the abort that PHP's parent::cleanChanges() raises when the
working copy has uncommitted changes. Drop the stub and give Git/Svn a
private fail_on_local_changes helper that performs the getLocalChanges
check and throws, matching the default VcsDownloader::clean_changes().
