[IMP] im_livechat : set livechat inactive _onCloseChatWindow

If the visitor closes the livechat window, he is redirected on rating /
feedback / send_transcript screen but he cannot go back to the conversation,
except by reloading the whole page.

Conversation should then be considered as inactive after the first click on X.

This commit close the conversation (set as livechat inactive and send the
'has left conversation' message) at first time the visitor closes the
conversation.
