[MartinBelthle]

Description

For example, it is possible to create a cluster that already exists. But when the variant is regenerated, it will fail with an HTTP 417 because the command is invalid (the cluster already exists).

Steps to Reproduce

Steps to reproduce the behavior:

1- Create a base study with 1 area and 1 thermical cluster
2- Create a variant
3- Create a thermal cluster of the same type with the same name on the variant -> It will add the command in the command list
4- Try to generate variant -> It will fail because the command is invalid

Actual Behavior

The variant is broken

Expected Behavior

The command should fail before being add to the command list
