ERROR: clear: Resources still in use at exit

At first: thank you all for the amazing engine!

I've found several similar issues, but it looks little different

Godot version:. v3.2.3.stable.official

Issue description:

ERROR: ~List: Condition "_first != __null" is true.
   At: ./core/self_list.h:112.

WARNING: cleanup: ObjectDB instances leaked at exit (run with --verbose for details).
   At: core/object.cpp:2135.
Hint: Leaked instances typically happen when nodes are removed from the scene tree (with `remove_child()`) but not freed (with `free()` or `queue_free()`).
ERROR: clear: Resources still in use at exit (run with --verbose for details).
   At: core/resource.cpp:477.
Resource still in use: res://Logger.gd (GDScript)

Steps to reproduce:
Please add below code into empty project and add it to AutoLoad.
Add export presses "Linux/X11".
Export it with next command:

godot --verbose --path ${PWD} --export-pack "Linux/X11" test.pck

extends Node
class_name LoggerNode

class TaggedLogger:
  var _logger: LoggerNode = null
  var _tags: Dictionary = {}

  func _init(logger: LoggerNode, tags: Dictionary):
    self._logger = logger
    self._tags = tags

func With(tags: Dictionary) -> TaggedLogger:
  """Extend logs with tags"""
  return TaggedLogger.new(self, tags)

Removing 'LoggerNode' type hints or removing the script from AutoLoad (of course attach it to any scene) solve the leak.

For syntax highlighting, use:

```gdscript

This prevents them from taking too much space and also makes sure issue references aren't accidentally created. I edited your comment, but remember to do this next time 🙂
