In test_ServerStopsReading, wait longer for the server to cancel the upload
Some recent server versions perform more readahead in COPY INTO.
This means that a query such as
COPY 10 RECORDS INTO foo FROM 'some-file' ON CLIENT
will upload much more data before the server finally decides it can
cancel the rest of the upload. When testing the cancellation
behavior we need to take this into account.
