Differences between expected and actual content in 3D asset imports

RTA tests show differences between expected and actual content in some 3D asset imports when imported in QDS4.1 latest snapshot. Please see attached diff files.

For example, some mesh file names have changed to "Electriccar_27k/meshes/untitled_006.mesh" instead of showing proper name e.g. "Electriccar_27k/meshes/body.mesh" -> selecting the correct model source is harder. See attached picture.
