The reason is that internally (regardless of the line endings that were in the original file), the Qt editor represents newlines with the Unicode character U+2029 (BLOCK SEPARATOR). So you need to use

  txt.replace(/\u2029/g, ' ');

to achieve what you're trying to do here.

(BTW, with the new script APIs you no longer need to ensure you return "undefined" from a QtScript to avoid getting a result dialog; to actually return something, you'd have to explicitly assign to TW.result.)
