Short description of error
Node wrangler fails to create mix node after attempting to use it in geometry nodes.

Exact steps for others to reproduce the error

open blender to default scene
create material on default cube: add difues shader, glossy shader, use node wrangler ctrl+shift+rmb to create mix node between them; everything works as expected
go to geometry node editor, add 2 color ramps
attempt to mix color ramps {key Ctrl Shift RMB}
fails with RuntimeError: Error: Node type GeometryNodeMixRGB undefined
go back to shader editor
delete previously added mix shader node, try to mix diffuse and glossy created at step 2 {key Ctrl Shift RMB}
node wrangler fails with KeyError: 'bpy_prop_collection[key]: key "ColorRamp.001" not found'

Workaround: bpy.context.scene.NWBusyDrawing = ""

I think the exception from line 1309 when attempting to use the node wrangler in the geo node prevents the script from reaching
context.scene.NWBusyDrawing = "" at node_wrangler.py line 1311 so the addon continues to work with an incorrect value
