libstore: remove Worker::topGoals

since we now propagate goal exceptions properly we no longer need to
check topGoals for a reason to abort early. any early abort reasons,
whether by exception or a clean top goal failure, can now be handled
by inspecting the goal result in the main loop. this greatly reduces
goal-to-goal interactions that do not happen at the main loop level.

since the underscore-free name is now available for use as variables
we'll migrate to that where we currently use `_topGoals` for locals.
