CV restitution tutorial is not working

The tutorial CV restitution is not working. Using the first command provided

./run.py --CI0 300 --visualize --np 2

results in the following error:

openCARP/external/experiments/2025-04-30__Gil-0.365_Gel-1.3111_CI0-300_CI1-500 does already exist...

It seems that restituteCV is using tuning.py internally, which fails in config due to missing/incompatible parameters in args. Have not investigated it further yet.
