    app: fix progress text when applying shaped gradient through PDB
    
    In gimp_drawable_gradient(), pass the undo description ("Gradient")
    to gimp_gegl_apply_operation(), so that its displayed as the
    progress text while rendering the gradient, even when applying a
    shaped gradient, in which case we end the progress after
    calculating the distance map, causing the progress text be NULL
    during rendering unless explicitly set.
