[fcomte]

An execption arise when suspend or resume on restricted catalog.

This is th result of this line : https://github.com/InseeFrLab/onyxia-api/blob/7152d9afa708e461d28eae49d6e0a3f7bfbac558/onyxia-api/src/main/java/fr/insee/onyxia/api/controller/api/mylab/MyLabController.java#L235

We should call the same method with a user parameter also.
