Some errors don't show proper details in debug console

[mysticfall]

Godot version:
master / eb9fa02

OS/device including version:
Manjaro Linux 17.1.1

Issue description:
In a C# project, some error messages do not show proper details in the editor console, while more relevant information can be read in the terminal, if Godot is launched from there.

For example, below shows how Godot displays two different errors in the editor console:

On the other hand, below shows what was logged in the terminal when the same errors occur:

ERROR: add_child: Parent node is busy setting up children, add_node() failed. Consider using call_deferred("add_child", child) instead.
   At: scene/main/node.cpp:1336.
ERROR: add_child: Parent node is busy setting up children, add_node() failed. Consider using call_deferred("add_child", child) instead.
   At: scene/main/node.cpp:1336.
Node has been detached from parent, or already disposed.

Steps to reproduce:
I encountered the problem when I tried to add a child node to the parent from another of its children inside its _EnterTree() callback, which apparently seems to be not allowed.

It's likely not Mono-related but a duplicate of #32276, which was fixed by #33517.
