Upgrading from 4.22 to 4.23 can break emitter inheritance

Copied emitters will have their inheritance broken when migrating from 4.22 to 4.23. 

1. In 4.22 create a Niagara emitter based on the fountain template
2. Create a Niagara system based on that emitter
3. Copy and paste the emitter a few times in the system
4. Change the spawn rate in the parent emitter, compile and apply
5. Go back to the system and see that all emitters reflect this change. They should all have buttons to navigate to their parent emitter as well
6. Save and exit
7. Open the project in 4.23, and open the system. Only the original emitter will have the button to navigate to the parent
8. Make changes to the parent emitter's spawn rate, compile and apply

RESULT

Only the original emitter will have the changes applied to it.
