Fix percent done on resumed /clone.bundle

The Content-Length when resuming is the number of bytes that
remain in the file. To compute the total size as expected by
the progress meter, we must add the bytes already stored.

While we are in this method fix uses of % operator to ensure
a tuple is always supplied.
