Got rid of 2 parameters in Response::build_404()

Instead of passing the `bookName` and `bookTitle` parameters to
`Response::build_404()`, `withTaskbarInfo()` is applied to its result
when needed. Note, that in `InternalServer::handle_raw()`
`withTaskbarInfo()` was not utilized since the results of the `/raw`
endpoint are not supposed to be decorated with a taskbar.
