Issue Summary

When submitting the schema and mapping for an external import with parent/child object types, the referenced object attributes are not created when those attributes refer to a child object type. 

Steps to Reproduce

1. Configure a new or existing object schema
2. Navigate to imports tab
3. Create an import configuration to "Connect another app" with a generated token
4. Generate token
5. Follow steps 1-2 as listed here (https://developer.atlassian.com/cloud/insight/imports/workflow/)
6. Use attached JSON to submit mapping as listed in step 3 (specifies parent object type with referenced objects of child object types)
7. View object type(s) in object schema

Expected Results

Object type structures are created with specified hierarchy and contain attributes of referenced objects.

Actual Results

Object type structures are created with specified hierarchy but do not contain attributes of referenced objects.
