In this threaded setup the server can sometimes have the data before it
calls "waitForReadyRead", what happens then is that we fail the wait and
as a result the test fails overall.
Let's check if we actually got some data after all and then continue if
we did. Since both the client and the server currently wait the same
amount of time (2s) the max timeout for the client was increased by
0.5s so it has some time to notice that the server got the message.
