Remove node-fetch, Replace with axios.

Remove node-fetch, Replace with axios. Shift try/catch logic into promise notation. Update relevant tests. Fix some minor syntax (semicolons, etc)

@gtibrett thank you so much for the PR. I think the try/catch notation looks better and is the common format used throughout the code - so I changed that part. Other than that the PR looks great, thanks again for the contribution 🥇
