kthelgason b83797bd7a Fix flaky ViEEncoder unit test.
The flaky test was introduced in ad9010c9836, and is essentially a race
where the ViE Encoder has already configured the quality scaler on the
encoder thread before we've updated the ScalingSettings. This CL adds
a forced reconfiguration of the quality scaler to avoid this issue.
