--[Bugfix] - Address ObjectInstanceAttributes save issues

[jturner65]

Motivation and Context

This PR addresses the SceneInstance-specified DefaultCOMCorrection specification not being properly represented when an object is created in an existing, running scene. This causes these added objects to not be saved at the appropriate location should the modified scene be saved to JSON.

How Has This Been Tested

Locally c++ and python
