Pandora memory leaks on exit

[shomykohai]

Godot version: 4.2-4.3

Describe the bug
Running an exported project with Pandora from terminal with the --verbose option, reveals lots of memory leaks (resources still in use).

To Reproduce
Steps to reproduce the behavior:

1. Export a project with Pandora that has some entities and categories set
2. Run the _console executable with the --verbose flag
3. Close the project without doing anything else
4. See the leaks

Expected behavior
Pandora clears all the resources before exiting.

Additional context
I reproduced the issue with my project and with cave-0.2.3-dev.
Here's the output of cave:

Furthermore, this could also be a Issue related to Godot and not Pandora itself, not sure though.
