Black light probes after duplicating baked geometry during the bake with CPU Lightmapper

Progressive Lightmapper

-

Jira card: https://jira.unity3d.com/browse/GFXGI-543

Steps to repro:
1. Open the attached project and 'ProgressiveLightmappingExample' scene;
2. In the Lighting window (Window>Rendering>Lighting) press Generate Lighting button;
3. Once the left bake time is visible in the progress bar in the Hierarchy select "SpiceBags02" gameobject and duplicate it (cmd+D);
4. In the Scene view move the duplicated gameobject with using transform gizmos;
5. Wait until GI bake is completed;
6. Observe the light probes in the Scene view.

Expected result:
The light probes in the scene are lit by the scene light.

Actual result:
Light probes in the scene are black. See attached video and screenshots.
Regression introduced in Version 2020.2.
Workaround is to clear GI Cache and baked data and rebake GI.
