ID 383496 - Trailing slash on the selectedMaterialTreeRootLocations parameter in LookFileBake nodes is not ignored

Problem summary

Trailing slash on the selectedMaterialTreeRootLocations scene graph path parameter causes the unassigned materials to not be included in the look file .klf on LookFileBake nodes. For example, "/root/materials/".

Steps to reproduce

3) View the LookFileMaterialsIn_Include node.

Notice in the Scene Graph tab that both assigned and unassigned materials are present.

4) View the LookFileMaterialIn_Include_Trailing node.

Notice in the Scene Graph tab that the unassigned material is missing.
