[FIX] im_livechat: show chat to operator only after first message

Not sure exactly because of which change, but channel partner is now created
with its default is_pinned value (True) taken into account, which was not the
case before. This is a good change in general, but the livechat code relied on
the old behavior.

This commit makes it explicit that in this case the value should be False, and a
test is added to guarantee it once and for all.

This commit also fixes an issue during init messaging, where ids of res.partner
were searched instead of ids of channel.partner.
