[FIX] (im,website)_livechat: visitor country displayed twice in backend

Before this commit:

At least if website_livechat is installed, the livechat visitor (website visitor)
country is displayed twice in channel name: once from the country inside the
name of livechat_visitor and once from the country of the actual
website_visitor.

After this commit:

Livechat visitor country will be displayed only once instead of twice
