yaml and deterministic tests

[dalinel]

@Timothee-ANNE has remarked that test_controller was not deterministic anymore
The issue seems to be that according to the order of the tasks in the yaml files we don't exactly have the same q output
The momentum task also generates non deterministics results, we need to check if those issue are linked

We should also add a test to check determinism

Determinism has been checked without the robot_dart and hence closed loop stabilization part
