question: Why do we need to delete the Scenario with the service instead of the repository?

[RomuDeuxfois]

Just to remove scenarioRepository from the class.
But, it's maybe not a good shot ?

TEST OK

• Creation of Challenge -> OK, No regression
• Update of a Challenge -> OK, fix works

I have a question regarding the values of Score and Max number of attempts, is it normal that I'm able to set negative numbers?
I updated my Challenge with a -0.43 Score and a -42 as Max number of attempts

Taking care of it
