### Issue description

Calling `tween_callback` where the first (object) parameter is a `Reference` doesn't work as I expected.  The code compiles and runs without producing any errors, but the callback function is never executed.

### Steps to reproduce

Running the minimal reproduction project demonstrates the issue.  The code pattern is quite simple:

**ReferenceType.gd**
```gdscript
extends Reference

func foo():
	print("foo was called")
```

**Test.gd**
```gdscript
extends Node2D

func _ready():
	var ref := preload("ReferenceType.gd").new()
	var tween := create_tween()
	tween.tween_interval(1)
	tween.tween_callback(ref, "foo")
```

I suspect that the issue is somehow related to reference-counting, and that `SceneTreeTween` is not updating the object's reference count.  I can get the behavior I expect by modifying the code to call `reference()` and `unreference()` manually, as shown below:

```gdscript
	var ref := preload("ReferenceType.gd").new()
	ref.reference()
	
	var tween := create_tween()
	tween.tween_interval(1)
	tween.tween_callback(ref, "foo")
	tween.tween_callback(ref, "unreference")
```

The documentation strongly recommends against calling these functions "unless you know what you're doing", so it feels like `SceneTreeTween` should handle this.  If this is expected behavior, it would be nice if the `SceneTreeTween` documentation urged caution when using `Reference`.
