[FIX] im_livechat, mail: hide call buttons for chat with visitor

Before this commit:

In Discuss topbar, call buttons are added to allow call and video between
channel members. Those buttons were also added to live chat channels but any
voice call or video call features are not available for visitors.

After this commit:

Call buttons will not appear in Discuss top bar for live chat channels.
