The test sometimes receives zero Merino suggestions when it expects some. I
noticed a few potential problems:

1. The merino.timeoutMs pref keeps its default value of 200ms throughout most
   of the test. That's low enough that it might cause the client to time out
   waiting for Merino, especially on slow machines in verify mode. To fix that,
   I set the timeout pref to a large value at the start of the test.
2. The Merino test server should probably cancel its delayed-response timers
   when reset() is called on it. Otherwise the server will still send
   responses once the timers elapse, which might interfere with later tasks.
3. I'm not sure about this, but the test server's #handleRequest() method
   probably shouldn't be async. Right now it's async to handle sending delayed
   responses. This patch makes it sync and it just handles that using a then()
   instead.

Retriggers on try are green.
