Fixing disconnect tone heard when merging 3rd participant into conference.

The issue was when we set the merge peer/merge host.  We were always
setting the merge peer to the BG call.  This is fine when there is no
conference, but when we already have a conference we need to take into
account whether the FG or BG is the conference.
