Fixing issue with automated ride hail getting simulations stuck

[HoneyTauOverTwo]

There is an issue with AV RH which was discovered on GEMINI but later was proven to happen on develop as well, although less frequently.

The test "Ride Hail Electric vehicles" should "pick chargers choosing smaller DrivingTimeCost." of ElectricVehicleChargingBehaviorTest sometimes gets stuck on CI. Investigation led to the conclusion that, at least for this particular test, the issue only appears when running multiple beam simulations in parallel (which is the case for CI).
