That's because the test was waiting for the end of the transfer for no
reasons, which ended after a timeout with an error. In this case, the
stats were displayed, but this error was ignored: the end of transfer is
not validated in this test.
To fix that, stop the transfer after the last check, similar to what is
done in the other tests.
