ATR-23722: Update nSteps property of Chain class when appending bjet steps
fixes bug found in ATR-23722.
before:
jet.steps = jet.steps + Bjet.steps
now:
also update jet.nSteps
, through use of function:
jet.append_bjet_steps(Bjet.steps)
function should protect against unanticipated use cases (e.g. already-merged chains). Should not change anything in the menu, because things it will change would not have compiled.
