When OBS Studio is started in Studio Mode, if a scene collection was not successfully found and loaded, the OBS Frontend API would, prior to obsproject/obs-studio@577e350, emit OBS_FRONTEND_EVENT_SCENE_CHANGED and OBS_FRONTEND_EVENT_PREVIEW_SCENE_CHANGED anyway. This would result in currentScene here being a nullptr, causing a crash. For completeness, check for nullptr here so that we cannot crash if obs_frontend_get_current_scene() returns a nullptr.

Description
When OBS Studio is started in Studio Mode, if a scene collection was not successfully found and loaded, the OBS Frontend API would, prior to obsproject/obs-studio@577e350, emit OBS_FRONTEND_EVENT_SCENE_CHANGED and
OBS_FRONTEND_EVENT_PREVIEW_SCENE_CHANGED anyway. This would result in currentScene here being a nullptr, causing a crash.
For completeness, check for nullptr here so that we cannot crash if obs_frontend_get_current_scene() returns a nullptr.
