An in-range update of core-js is breaking the build 🚨

## The dependency [core-js](https://github.com/zloirock/core-js) was updated from `3.2.1` to `3.3.0`.

🚨 [View failing branch](https://github.com/aethant/merino/compare/master...aethant:greenkeeper%2Fcore-js-3.3.0).

This version is **covered** by your **current version range** and after updating it in your project **the build failed**.

core-js is a direct dependency of this project, and **it is very likely causing it to break**. If other packages depend on yours, this update is probably also breaking those in turn.

- ❌ **continuous-integration/travis-ci/push:** The Travis CI build failed ([Details](https://travis-ci.org/aethant/merino/builds/597279186?utm_source=github_status&utm_medium=notification)).
