Resources still in use at exit

[Cyxo]

System Info

• Godot Version: 3.3.2
• Operating System: Windows 10
• Compilation Method: I used the precompiled versions from the demo and github actions (release)

Describe the bug

I get the following message when closing the game (see below for the verbose log):

WARNING: cleanup: ObjectDB instances leaked at exit (run with --verbose for details).
     At: core/object.cpp:2132
ERROR: clear: Resources still in use at exit (run with --verbose for details).
   At: core/resource.cpp:450

To Reproduce

1. Create the core in _ready
2. Update the activity in _ready
3. Run the callbacks in _process
4. Close the game (using Alt+F4 or calling get_tree().quit())

Expected behaviour

No leaks

I am aware of this issue, and it seems to be a problem with how Godot is dealing with the references.
I will look for solutions, but this is something I have been unable to resolve for a while.

Been experimenting with using godot-rust, I think the rust rewrite should fix this issue
