Format issue with /ReadMyUser servlet

[Nouxx]

Hello,

According to https://qa.cerberus-testing.org/ReadMyUser call

• defaultSystem attribute is weirdly formatted when several ones are selected

I would recommend a list of Invariants :

"defaultSystem": [
        {
            "value": "CERBERUS",
            "description": "desc",
            "gp1": "",
            "gp2": "",
            "gp3": ""
        },
        {
            "value": "EXAMPLES",
            "description": "desc",
            "gp1": "",
            "gp2": "",
            "gp3": ""
        }
    ]

• same comment with system attribute (which is currently an array of string)

Thanks
