Any reference to a node that was script assigned with SetScript (), is invalid

[Torguen]

Godot version:

3.2.4 rc1 mono

OS/device including version:

win10 64

Issue description:

A node is lost when a script is assigned to it with "SetScript ()".
References to that node will not be valid.
Normally the run window closes immediately when it appears and nothing else happens, however sometimes the editor shows this error:

If line 13 is commented out, then no error occurs.
On the other hand, if line 13 is commented, it can be seen in remote mode that the "script" property is displayed duplicated.

Steps to reproduce:
Create a class without code.
Create a node, for example of type Node.
Create a script and in _Ready create a new node type object.
Then assign it the initial script that had no code.
Call "SetProcess (true)" of the newly created node.
Run.
The run window will close automatically at startup, but may occasionally the editor shows the initial image error.
Test project code, line 13 causes the error:

Minimal reproduction project:

The ObjectDisposedException is expected behavior. When you call SetScript on nodo, nodo isn't valid anymore. See #31994 (comment) for more details, and a way to get a reference to the new node that Godot creates when you call SetScript.

However, in most cases you don't actually need SetScript, anyway. It looks like you can just call new ScriptSetted(), which is a lot simpler:

nodo = new ScriptSetted();
AddChild(nodo);
