Description

Steps to reproduce:

1: From the root group create a Controller Service (ie. HttpContextMap)
2: Create two child process groups
3: In each child group create a processor that references the CS (ie. HandleHttpRequest and HandleHttpResponse)
4: Create a template of the two child PGs
5: Export the template
6: Import template into a clean instance
7: See the Controller service not scoped to the root level but instead scoped to one of the child PGs

I believe the template creation is grabbing the first instance of the CS when it sees it and ignores the other references, instead of taking it at the highest level. I also believe this is related to NIFI-3129
