_reload_scene() is using free() instead of queue_free()

[mouring]

Change to queue_free() to free() otherwise calling fade_out() too close to change_scene() results in a game crash as the object is still being locked waiting for signals to be completed.

e.g.

SceneManager.fade_out()
SceneManager.change_scene(
	'res://demo/test.tscn', {
		"pattern_enter": "diagonal", 
		"pattern_leave": "curtains", 
		"invert_on_leave": false,
		"skip_fade_out": true,
	}

Unless you change the line to yield(SceneManager.fade_out(), "complete") or add in "yield(SceneManager, "fade_complete").
