NIFI-3764: Ensuring that UUIDs are not converted multiple times during
template export
NIFI-3764:
- Ensuring that UUIDs are not converted multiple times during template
export.
This was causing an issue because components were being set in the exported
template successively which the already converted UUID to be converted again.
This resulted in component duplication and the lose of association between
components that referenced services.

>
> If components reference a Controller Service from a nested Process Group, the
> exported template will be incorrect. Specifically, it appears that the
> service is duplicated and the Processors that reference it are no longer
> configured with the appropriate UUID. The issue is resulting from the code
> that converts the internal data model into a template assuming behavior that
> was incorrect and addressed as part of NIFI-3509.
