      Description

      If one runs a task, then retargets a subtask and tries to run it again without --clobber-config, the resulting comparison can throw an exception if the two subtasks have differing config schemas. An example traceback is pasted below. This should not be an exception, and should be treated as the comparison returning nonequal.
