When SUP client receives some files and not completes it for some
reasons (e.g. SUP server cannot read one of the files due to
permission error), SUP client aborts and doesn't correctly update the
"$BASE/$COLLECTION/last" file. (even if some files are actually
So, if the newly received files (which are created in such failed
transaction) are removed in SUP server, SUP client doesn't think the
files are received from server, and doesn't remove the files.
