LiveSceneTest: Adjust for updated MeshAlgo::segment

Commit 0195899 updated
`MeshAlgo::segment` to use the new `MeshSplitter` introduced in commit
bf2040e.

The MeshSplitter does not preserve Vertex order as of now, which leads
to changes in corner and crease Ids.

NOTE: The round trip from Houdini Geometry to a Cortex MeshPrimitive
and back to Houdini Geometry still works correctly. Corner and crease
data is applied at the correct point positions, just the point number
changes
