Fixes a bug in which indexed normals are not correctly added to maya meshes. Maya expects fully expanded face varying normals when using the function `MFnMesh::setFaceVertexNormals`.
The test was failing for two reasons: 1. The meshMerge op could not be found 2. `IECoreScene::MeshPrimitive::createBox` uses indexed normals. However, ToMayaMeshConverter was not correctly converting them, and then when the scene was reloaded maya was automatically recalculating them.
