Consider removing Axios in favour of node-fetch

[nickytonline]

fetch is not native in Node yet (I think they're working on it), but there is node-fetch.

It has a way smaller footprint than Axios and the extra stuff Axios provides is not required in the project from what I can tell. This change would also require pulling out the axios-mock-adapter package and replacing it with most likely jest-fetch-mock.
