### Issue description

Accessing a scene unique node like this:
```gdscript
class_name Class extends Node
static func get_label() -> Label:
	return %label
```
and then accessing that class later:
```gdscript
func _ready() -> void:
	Main.get_label().text = "hello world"
```
causes a strange error when in the editor, and a normal error when run directly.

```c++
ERROR: Node not found: "%label" (relative to "/root/main").
   at: get_node (scene/main/node.cpp:1364)
```
Instead of returning null.
As opposed to when using `get_node`:
```

SCRIPT ERROR: Cannot call method 'get_node' on a null value.
          at: get_label (res://main.gd:5)
SCRIPT ERROR: Invalid set index 'text' (on base: 'Nil') with value of type 'String'.
          at: _ready (res://control.gd:4)
```
