    roster-view: clear_view: start by cleaning our internal hash tables
    
    Removing and destroying the widgets contained in the view will call
    empathy_roster_view_remove(). This function may use some of the internal hash
    tables which now contain destroyed object.
    
    It's safer to clean the internal hash tables first as we are about to destroy
    their content anyway.
