Through tasks not properly logging

[tiagofilipe12]

While doing my GSoC17 Week 12 report noticed that through tasks properly handle input and output but it does not have resolvedInput properly logged to graphson.json and there is no node in graph visualization in d3 (localhost:8084). Also, last redux state seems to not have resolvedOutput but has resolvedInput.

Maybe something is lost in the middle of through...

Potentially related to #79 .
