tracing_service_impl_unittest: Rework timing of internal checks In a future commit, the service will not observe consumer calls immediately, but only after a TaskRunner::PostTask. In tha case we cannot check internals of TracingServiceImpl immediately: we have to wait. We can simply wait for the effects to be visible on the producers and then check the internals.
