Fix Readline.get_screen_size before Readline.readline

It was missing a check for the lazily initialized holder.readline. I also added one in Readline.refresh_line which also accessed holder.readline without the check.

Without this, calling Readline.get_screen_size before calling Readline.readline raises a NullPointerException:

```
