Versioned sources were added in commit
b2302902a3b3e1cce140a6417f4c5e490869a3f2 after the scene collection
importer was added in commit 191165c7210f2b8adf8756cf121341075bf16b3d.
When a versioned source gets converted in TranslateOSStudio, it can end
up with a translated "id" but an untranslated "versioned_id". When OBS
loads the resulting JSON, it will rely on the versioned_id, and rewrite
the id to the corresponding value. Use obs_get_latest_input_type_id on
the translated source id to get the correct versioned_id when using
TranslateOSStudio.
