[Simulation] Counter not reset when a new simulation is started
- open the traffic light
- start a simulation through the context menu
- apply one step
- observe that the counter is at 1
- go back to modeling perspective
- start again a simulation through the context menu
Observe: counter is still at 1 (but the input value does not has NoVal anymore, proving that the simulation is indeed again at 0)
Expected: counter should be at 0
