[155] Reset changes of 'Subsequent' probability attributes

All changes being made to a relation of type 'Subsequent' especially
regarding to its probability attributes are being reset to the standard
values if the preceding object is not of type 'DecisionNotSpecified'.
That is particularly important due to the fact that it should only be
possible to assign a probability to a 'Subsequent' relation in case
it is a branching.
