    Test that the Query class' 'start' argument works
    
    Reading our Query class I became worried that our 'start' argument fails to get
    honored because the start() method is asynchronous (so its invocation returns a
    coroutine rather than running it).
    
    I was wrong. It works because as a Synchronous subclass our metaprogramming
    converts the call. That said, this is none the less a good thing to check.
