#2190:
When setting the available operators for the MultiVRPMoveGenerator the AlbaOperators and the PotvinVehicleAssignmentMultiMoveGenerator are unchecked by default.
The AlbaOperators doesn't work with a TabuSearch as they do not specify a TabuChecker.
The PotvinVehicleAssignmentMultiMoveGenerator only makes sense for VRP instances where the Vehicles have different capacities and otherwise results in an empty neighborhood very quickly and the TabuSearch will stop although other Moves from the MultiMoveGenerator were possible.
