libobs: Allow duplicate sources per scene

Browse Source 
Previously having a source multiple times in a single scene would cause
the recursion check to trigger. Example scenes.json:

{
    "current_scene": "Scene",
    "sources": [
        {
            "flags": 0,
            "id": "scene",
            "mixers": 0,
            "name": "Scene",
            "settings": {
                "items": [
                    {
                        "align": 5,
                        "bounds": {
