[core] Error when renaming a node on dev

What commit version of aidge do you use

• aidge_core: dev

Problem description

I get an error when renaming a node saying it already exists in a no-name graph but it should not exist at the moment.

import aidge_core

model = aidge_core.sequential([
    aidge_core.FC(in_channels=32*32*3, out_channels=512,  name='0'),
    aidge_core.ReLU(name='1'),
])

for node in model.get_nodes():
    print(node.name())
    node.set_name(node.name() + "_lower")

Result:

0
Assertion failed: mNodeRegistry.find(newName) != mNodeRegistry.end() in C:\Users\AL253370\Documents\Projets\DeepGreen\aidge\aidge\aidge_core\include\aidge/graph/GraphView.hpp:411
Name 0_lower is already used in graph .
Traceback (most recent call last):

    node.set_name(node.name() + "_lower")
RuntimeError: Name 0_lower is already used in graph .

This works on main and used to work a few commits back on dev as well.
