[NIFI-8044] Controller services do not refer to any component when they are not associated with a top-level process group

Description

After the import of a versioned flow, the controller services configuration page (SETTINGS) says that it does not refer to any component if the controller services are defined in a scope higher than the first level.

Scenario
I have a process group (I will name it B) nested in a process group (that I will name A) that is at top-level. So they will be:
NiFi Flow » A » B
In process group B, it is defined at least one controller service (scope B) which refers to at least one component (Component_B) in this process group.
Process group A is versioned with the name FlowA.

Issue
When I import FlowA from the registry, the service at scope B says "No referencing components" on the settings page. Also, if I try to enable it, the same text "No referencing components" is shown under the "Referencing Components" label.

Expected behavior
When I import FlowA, the service at scope B should list the processors and/or controller services that refer to this service.
