'npm run test' and 'node-lambda run' behaves subtly differently

[TrashPanda]

It happens to me when the logs didn't show up as expected after I installed a few dependencies and the size of the folder increased quite a bit. After a few trials and errors it turned out that 'npm run test' and 'node-lambda run' were indeed giving different outputs. I am not sure why but I think that this bug might not be worth fixing. It might be better to just let the users to use the node-lambda cli commands.
