Foliage components will be unbuilt even after deleting all of the placed foliage in a level.

Found in 4.20 CL# 4369336, 4.21 CL# 4753647, 4.22 CL# 4827620

Steps to Reproduce
  1. Open the Editor
  2. Create a foliage type out of any static mesh
  3. Go to the foliage tool and add the foliage you created
  4. Place a single instance of the foliage and build lighting
  5. Using the select tool, select the single instance and delete it
  6. Build lighting again

Any future lighting builds will have this unbuilt unused component even when all the placed foliage has been removed.

Lighting will build with no errors
