Fix tests for 0.7.0

- tests should now convert actual and expected output to json and do a deepEquals. this is in case the path keys are in a different order.
- bump package.json from 0.6.0 to 0.7.0 (missed from previous commit)


doing a PR for this to make sure it passes through Travis ok. It seems to be working on my fork's travis instance but just wanna double check.
