Artifacts after baking GI with certain lighting settings and denoising enabled



Steps to repro:
1. Download the ArchViz Pro vol.6 project (link attached in the comments) and sync to revision `8546d9d7f07d` of the 'DenoisingBug' branch;
2. Open 'AVP6_Desktop' scene;
3. In the Preferences window (Edit>Preferences>GICache tab) click "Clean Cache" button;
4. In the Lighting window (Window>Rendering>Lighting) press the arrow button near the Generate Lighting button and select "Clear Baked Data";
5. In the Lighting window press Generate Lighting button;
6. Observe the Game View window after the baking is completed.

Expected result:
The scene with baked lighting is rendered smoothly without artifacts.
