derivation goals' addWantedOutputs is supremely sketchy and indicative of design mistakes. this function leads to the modify callback in makeGoalCommon existing at all, which is only needed for derivation goals (the substitution goals are already well-behaved).

goals should not be forced to restart after they have started work(), which is what addWantedOutputs implicitly does.
