Unpack prefab variant loses all references to the prefab
How to reproduce:
1. Open the "TestPrefabVariantUnpack" project
2. Open "SampleScene" from Assets > Scenes folder
3. Select "ReferenceToC" GameObject from the Hierarchy window and observe that it has a reference to "MyPrefabC"
4. Open "MyPrefabC" from the Assets folder
5. Right-click "MyPrefabC" in the Hierarchy window
6. Select "Unpack Prefab" ("Prefab" > "Unpack" in 2020.1.0a5 and later versions)
7. Save the Prefab and return to the "SampleScene"
8. Select the "ReferenceToC" GameObject from the Hierarchy window
Expected result: "ReferenceToC" GameObject still has a reference to "MyPrefabC" just like in the 3rd step
Actual result: "ReferenceToC" GameObject no longer has a reference to "MyPrefabC"
Reproducible with: 2018.4.22f1, 2019.3.12f1, 2020.1.0b8, 2020.2.0a9
Could not test with: 2017.4.40f1 and earlier (no Prefab Variants)
Notes:
-The reference is also lost in the "ReferenceToC" Prefab in the Assets folder
