Reproduce:
1)Create a simple stack with nova server, then
2)create a stack using this template https://github.com/openstack/heat-templates/blob/master/hot/mistral/templates/stack_restarter.yaml
Send heat resource signal to start workflow resource created in step 2 and delete nova server that was created in step 1 manually.
