I am trying to fix this and now I remember what didn't work without that bool.
The point is that launchQuery resets() the context, hence it is launchQuery itself that sets the single runner query mode; thus it makes little sense to check RunnerContext::singleRunnerMode(); and I am not sure if assuming that the empty query should always be substituted if a runner is specified would break other apps.
What should I do then? keep the bool? any alternative solutions?
