uclamp and taskgroup mix issue

[douglas-raillard-arm]

Parsing this configuration:

    "tasks" : {
        "task1" : {
            "loop" : 1,
            "phases" : {
                "1" : {
                    "policy": "SCHED_OTHER",
                    "taskgroup": "/",
                    "run" : 3
                },
                "2" : {
                    "util_min": 512,
                    "run" : 3
                }
            }
        }
    },
    "global" : {
        "default_policy" : "SCHED_OTHER",
        "duration" : 1,
        "gnuplot" : false,
        "logdir" : "./",
        "log_basename" : "testrtapp",
        "lock_pages" : false,
        "frag" : 1,
        "calibration" : 63
    }
}

Fails with:
