The OpMsgFuzzerFixture resets the AuthorizationManager, which is a decoration on ServiceContext, after starting storage controls (i.e., startStorageControls). Starting the storage control enqueues a periodic task (i.e., JournalFlusher) that may attempt to access the AuthorizationManager, causing a data-race.

We should reset the AuthorizationManager immediately after creating the new instance of ServiceContext (here) to avoid the data-race.
