Short description of error
aov output node has an input parameter called 'name' this conflicts with the node.name used to change the name of the actual node.

This means that when you set the node name via python using:

new_node = bpy.data.node_groups['.my_Group'].nodes.new("ShaderNodeOutputAOV")
new_node.name = 'hello'

you can't then reference the node by name using:

n = bpy.data.node_groups['.my_group'].nodes['hello']

because it'll return error:

KeyError: 'bpy_prop_collection[key]: key "hello" not found'

Exact steps for others to reproduce the error

open attached blend file
go to the script workspace
run the script

I believe the aov output node's 'name' input parameter should be:

bpy.data.node_groups['.my_group'].nodes['hello'].inputs['name']

rather than it being set by node.name.

Or alternatively, setting the node.name should set both the name input parameter and the node's name?
