    Fix problem with qualify option packets for realtime peers never stopping.
    
    The option packets not only never stopped, but if a realtime peer was not in
    the peer list multiple options dialogs could accumulate over time. This
    scenario has the potential to progress to the point of saturating a link just
    from options packets. The fix was to ensure that the poke scheduler checks to
    see if a peer is in the peer list before continuing to poke. The reason a peer
    must be in the peer list to be able to properly manage an options dialog is
    because otherwise the call pointer is lost when the peer is regenerated from
    the database, which is how existing qualify dialogs are detected.
