Set tnu and leonard to dummy values when we have_les without dynamic_les
Set tnu and leonard to dummy values when we have_les without dynamic_les

If have_les is true, but dynamic_les is false, then tnu and leonard
will be unassociated on entry into the assembly loop.  Set them to
dummy vector and tensor quantities in this case.
