[FIX] im_livechat: bad coping of chatschript

Before this commit when you copy a chatbot script, the triggering answer are mixing.

- Create a chatbot
- Create a line A - question ligne with one response 1
- Create a line B - type text
- Create a line C - type text
- Save
- Invert line B and C
- on ligne C add response 1 in triggering answer
- Save
- Copy the script
--> Issue the response 1 in triggering answer is now in line B
