LP#1224647: remove two invalid tests

The patch for bug 1204123 changes the client_recv()
to not set the transport_client error flag, as most
of the circumstances where it would have been set were
for cases where the call to select() was interrupted
by a signal, which is not an error per se.

This patch removes two tests that were therefore
made invalid, restoring the ability of the test suite
to pass.
