Node scenario is failing to run multiple actions

[chaitanyaenr]

Krkn is running only the first action instead of running all the actions defined in the scenario config. For example, krkn run is ending after the node_stop_start_scenario for the following configuration:

"parameters": {
                    "node_scenarios": [

                        }
                    ]
                },
