    Make sure that we unref the correct object when ejecting the most recent caller.
    
    Currently, when we kick the last user to enter, we decrement our own reference
    count which results in a crash when we kick another user or when we exit the
    conference ourselves.
    
    This will fix #18225 in 1.8 and trunk, but that particular bug does not exist in
    1.6.2.
    
    (closes issue #18225)
