prelude-correlator/master: Fix rare IDMEF:Set() exception

    Fix rare IDMEF:Set() exception
    
    A rare exception would occur when IDMEF:Set() was called with
    an empty list/tuple as the value argument. This case is now
    handled specificaly for consistancy with IDMEF:Get() (which
    can return an empty tuple in case the retrieved path is empty
    and ambiguous).
