Prevents a client adding messages without calling error or info on
TestNotifier by modifying the Lists returned by getInfoMessages and
getErrorMessages.
More immediately usefully, saves a client from getting
ConcurrentModificationExceptions when iterating over the List returned
by those methods if other threads are concurrently altering them, which
should stop WebhooksAcceptanceViaPostServeActionTest.firesASingleWebhookWhenRequested
(and others?) being flaky.
