Inspect code for bugs that are not covered by tests

After #39

The code in https://github.com/Palindrom/JSONPatcherProxy/blob/c461b492a4fa2e2869ba99cbe0329db3846e93cd/src/jsonpatcherproxy.js contains several TODO statements that mark places for functionality that is not tested.

Also check why running the test suite results in so many console loigs. Is this by design, or are some of these console logs actually pointing out a problem:

λ npm run test

> jsonpatcherproxy@0.0.10 test W:\repo\JSONPatcherProxy
> jasmine DUPLEX=proxy JASMINE_CONFIG_PATH=test/jasmine.json
