Child GameObject is moved to an active Scene when setting the child GameObject's parent to null and the current parent GameObject is deactivated

How to reproduce:
1. Open the user's attached "transform-parent-repro.zip"
2. Open the "SampleScene" Scene
3. Go to Bug Repro -> This does not work
4. Observe the Hierarchy window

Expected result: One activated GameObject and one deactivated GameObject is created in the "SampleScene" Scene
Actual result: Only the deactivated GameObject is created in the "SampleScene" Scene (Child GameObject was moved into a different Scene)

Reproducible with: 2018.4.27f1, 2019.4.10f1, 2020.1.5f1, 2020.2.0b2

Note:
- The issue is not reproducible if the child GameObject is inside an activated parent GameObject
