UV Charts Baked GI scene visualization mode is working incorrectly in Enlighten

Steps for reproduction:
1) Download the project below or create a new scene with a baked light and a lightmap static object
2) Generate the lighting
3) Switch the scene visualization mode from Shaded to Baked GI > UV Charts
4) Observe the artifacts and wrong display. Instead of UV charts, baked lightmaps are displayed
5) Switch the bake backend to Progressive Lightmapper and generate the lighting again
6) Observe the correct display. UV Charts are displayed correctly in the scene view

Notes:
- Not a regression. New Scene VIsualization modes are introduced with 5.6.0b6
