nit: just stick webError.message in there too, even though we should never reach
that code.

Done.

     case WebPushError::ErrorTypeNotAllowed:
       return DOMException::create(NotAllowedError, webError.message);
     case WebPushError::ErrorTypeNotFound:
       return DOMException::create(NotFoundError, webError.message);
     case WebPushError::ErrorTypeNotSupported:
       return DOMException::create(NotSupportedError, webError.message);
-    case WebPushError::ErrorTypeUnknown:
-      return DOMException::create(UnknownError, webError.message);
   }
   NOTREACHED();
   return DOMException::create(UnknownError);
 }
