runBackup takes a library object from its caller. One whose
contentConcurrency is missing, 0 or negative starts no worker, so the
backup stores no original and reports no error. The test expects
runBackup to reject any limit that is not a positive integer, as
BoundedPool does, before it takes the lock, which would create the
download directory. Today it takes the lock and fails on the first method
the object lacks.
