fix the repair mode
fix the repair mode

if one used --last (or since shortly: gave an archive name), verify_chunks (old method name) was
not called because it requires all archives having been checked.

the problem was that also the final manifest.write() and repository.commit() was done in that method,
so all other repair work did not get committed in that case.

I moved these calls that to a separate finish() method.
