Parallel queries executed without the leader participation won't execute the sub nodes in the Gather/GatherMerge, which is represented by need_to_scan_locally=false. Since the nodes won't be executed, we won't have a traced plan and there's no value to generate spans from those nodes. Just skip the whole subtree in those cases. Fixes #54
