api2: tape/restore: commit temporary catalog at the end

in 'restore_archive', we reach that 'catalog.commit()' for
* every skipped snapshot (we already call 'commit_if_large' then before)
* every skipped chunk archive (no change in catalog since we do not read
  the chunk archive in that case)
* after reading a catalog (no change in catalog)

in all other cases, we call 'commit_if_large' and return early,
meaning that the 'commit' there was executed too often and
unnecessary, so move it after the loop over the files, before
finishing the temporary database.
