    pdb: in plug_in_compat.pdb, set underlying op nodes
    
    In plug_in_compat.pdb, when wrapping an op node inside a graph, set
    the op node as the graph node's underlying operation.  This allows
    gimp_gegl_apply_operation() to perform certain optimizations.
    
    (cherry picked from commit e74994feafd277555c364067b26c575130252283)
