Sometimes restic gets bogus timestamps which cannot be converted to JSON, because the stdlib JSON encoder returns an error if the year is not within [0, 9999]. We now make sure that we at least record _some_ timestamp and cap the year either to 0000 or 9999. Before, restic would refuse to save the file at all, so this improves the status quo. This fixes #2174 and #1173
