Using web-test-runner for tests, updating import paths (#1242)
* WIP moving tests to web-test-runner

* updating thresholds

* Adding file extensions

* Testing integrations

* linting

* fixing dep

* moving back to root dir

* prettier all of the files

* updating eslint rules to use with prettier

* remove import package

* moving tsignore around

* removing unneeded ignores

* all tests run on puppeteer, no need for testing guards

* linting

* import type syntax

* cleaning up

* Update package.json
