Calibration: Diversion is not handled on upstream nodes

The diversion is not taken into account during calibration at least on upstream nodes.

On this small example below, if we define a huge Diversion flow in the node "54095" in order to derive the totality of the flow, the node should not be able to be calibrated because the resulting flow Qsim at the node "54095" should be zero.
