Upgrades jest to v27

* Upgrades `jest` from v26.4.2 to v27.5.1.
  * [CHANGELOG](https://github.com/facebook/jest/blob/v27.5.1/CHANGELOG.md)
  * v27 introduced breaking changes that had to be addressed.
* Upgrades testing-related dependencies, removes unused dependency
`babel-plugin-istanbul`, and replaces `jest-environment-jsdom-thirteen`
with the built-in `jest-environment-jsdom`.
* Skips a few flaky tests that need require additional investigation.

Resolves #1231
