I think that this is an error in the `guard_condition.cpp` code. Calling `rcl_trigger_guard_condition` should be independent from whether there is an `on_trigger_callback_` or not.

It looks like the `wait_for_message` API requires that the node is not already added to an executor, right? (otherwise you would have a node in 2 waitsets) This essentially means...
