workflow engine: append factory to set workflow status to running after merging maint-0.7 to master #255
Description
Stems from reanahub/reana-workflow-controller#363
Kubernetes starts the workflow-engine pod -> the workflow engine itself sets the status to running when it starts its execution (adding it to the factory create_workflow_engine_command so all workflow engines behave the same)
Make sure all the engines sets the workflow status to running by appending the factory
