Make the QEXPECT_FAIL agree with the QVERIFY2 condition below

Even if the system is not under high load, this test can generate 4
updates on Windows. This is seems to be because the timer actually
triggers before its supposed to (sometimes the second start() triggers
an update right before the animation is done (at timestamp 399 for
instance), forcing it to generate yet another timer event in order to
reach the end)).

Under high load conditions, too many things can break this test,
usually it finishes even before the pause(), causing the
QVERIFY(animation.state() == QAbstractAnimation::Paused);
to fail.
