multi: fix memory leak when stopped during name resolve

When the application just started the transfer and then stops it while
the name resolve in the background thread hasn't completed, we need to
wait for the resolve to complete and then cleanup data accordingly.

Enabled test 1553 again, added test 1557 to also check when the host
name resolves successfully.
