vtkMolecule: Do not leak scalar arrays
vtkMolecule: Do not leak scalar arrays

In vtkMolecule::Initialize we allocate two vtkUnsignedShortArray
instances for atomicNums and bondOrders.  Use vtkNew<> to avoid leaking
the reference returned by ::New().

This addresses vtkDebugLeaks warnings in TestEmptyInput and TestSetGet.
