    engine: Use JS_InitWithFailureDiagnostic instead of JS_Init
    
    No difference between these two, except that JS_InitWithFailureDiagnostic
    returns a descriptive message if it fails, which JS_Init ignores. So, in
    the rare case that it fails, we abort while printing the descriptive
    message instead of just "Could not initialize JavaScript".
