The merging behavior of having both `plugins` and `env.test.plugins` in the Babel configuration is confusing and does not work how we would like (that is, disabling the idx Babel plugin in test environments.) There had been some [discussion about deprecating the `env` key in Babel](https://github.com/babel/babel/issues/5276) because of this behavior and recommending using conditional logic. The behavior has been modified in later versions of Babel, but still does not work as intended in our case. Change this to only add the idx plugin if we're in a non-test environment.
