Chore: Replace tape with tap in tests

[nelsonic]

All the @dependabot PRs attempting to update tape https://www.npmjs.com/package/tape (the testing library) fail
because tape made a few (totally unnecessary) breaking changes ...
tap https://www.npmjs.com/package/tap a less popular but similar functionality alternative has not made those changes.

Todo

• update tests to replace tape with tap

See: dwyl/aws-sdk-mock#322 which updates tap without any issues. ✅

Tests pass but eslint doesn't ...

🤦‍♂️

Tried updating a couple of test files from tape to tap on a @dependabot PR that was failing: #427

The response.statusCode changed from 401 to 404 on a couple of tests where the server didn't change at all.
This is very weird. Not got time to be spending on this right now.
If anyone else wants to help with migrating from tape to tap, please dive in! 🙏
