The way this test was written didn't guarantee a deterministic message order, resulting in different output in Chromium and Firefox. This change slightly rearranges the message order to make it deterministic. This change is necessary as a prepartion for upcoming change that makes MessagePort post messages from a separate thread, which would've revealed the non-deterministic message order.
