With CommandTask, experiment must have an asset to run

[ZDu-IDM]

Repo test:

        command = "python -m pip list"
        task = CommandTask(command=command)
        sim = task.to_simulation()

        experiment = Experiment(name='test')
        experiment.simulations = [sim]

        self.platform.run_items(experiment)

Error
