developer_panel: adopt_visualizers reads only

Writing to a visualizer after the node's parm interface changed in the
same session crashed Houdini 22.0.429 in VIS_Table::writeMountDataToNode,
twice: once via setName, once via setParm after removeSpareParms.
Adopting an old instance now only fills the multiparm; the visualizers
are left as Houdini restored them.
