Steps to reproduce:
1) Make a flow with CS in root PG, and CS in child PG references the CS in
parent
2) Version control to registry
3) Delete everything from NiFi side
4) Import flow from registry, now have single CS in child, referencing missing
CS
5) Issue curl command to enable services on the child PG:
curl -H "Content-Type: application/json" -X PUT --data "\{ \"id\" :
\"5eddbdcc-0177-1000-22fe-321b6445813b\", \"state\" : \"ENABLED\" }"
