When a light that uses lighting channels is only visible in one view during stereoscopic rendering, it affects the default light channel instead of the assigned one in the view that it's not visible in. Happens both with and without instanced stereo enabled.

Found on //UE4/Release-4.11 CL-2944320

Steps to Reproduce
  1. Download the attached umap and replace VRTest in QAGAME with it.
  2. Open UE4Editor.exe QAGAME VRTest
  3. Play in VR Preview
  4. Move your headset left and right across the red-spotlight crates.

Alternatively, set up a map with some moveable objects set to lighting channel 2 only, with a spot light set to lighting channel 2 only as well. Then move the headset left to right across the objects, so that one eye cannot see the objects or light.
