braynsService logs a warning when loading a point cloud dataset

[rolandjitsu]

Describe the bug When I load a point cloud dataset, the service logs the following warning:

Warning: creating an instance to a model that does not have a valid bounding box. epsilons for ray offsets may be wrong (only reporting first occurrence)

Steps To Reproduce Steps to reproduce the behavior:

1. Start braynsService with no models
2. Use the web UI to connect to the service
3. Drag 'n' drop the point cloud dataset in the web UI
4. Check the braynsService terminal log

Expected behavior There should be no warnings 😄
