fix for (I assume) some inconsistency with gradio sometimes-but-not-all-the-time coercing an empty Textbox into an empty string or sometimes None, but I also assume that might be a deserialization issue from JSON (cannot be assed to ask people to screenshot UI or send their ./config/generation.json for analysis, so get this hot monkeyshit patch)
