General fixes to dependencies, tests and code to be able to run tests

[cvarela-usesi]

What problem is this solving?

When working with an app forked from this main repo, I was unable to run tests from root directory, and when ran from node directory, there were several failed tests.

I also was unable to run lint from there.

With the changes made, now both lint and tests can be run with yarn

How should this be manually tested?

This can be manually tested this way from root (please make sure you have this version for yarn: v1.22.10):

yarn test
