tst_QTcpSocket: fix disconnectWhileLookingUp

... and unblacklist it on Windows.

From what I can tell there is no particular reason why this test fails
other than that it is a little too slow sometimes (these things happen).

So, to fix the test I bumped the timeout, but to avoid the test running
for longer on every test-run it now also ends when the socket enters
the "Unconnected" state.

Previously it failed 171/500 times, and after this patch it failed
0/1000 times.
