**What is the current behavior?**
The `useState` hook's value is shown as `undefined` in React DevTools if the value is a string or a number. Clicking on the bug icon prints the correct values to console.

**If the current behavior is a bug, please provide the steps to reproduce and if possible a minimal demo of the problem. Your bug will get fixed much faster if we can run your code and it doesn't have dependencies other than React.**

**What is the expected behavior?**
The DevTools should show the correct value of the hook.

**Which versions of React, and which browser / OS are affected by this issue? Did this work in previous versions of React?**
React 16.9.0.
Google Chrome [Version 77.0.3865.90 (Official Build) (64-bit)] running on Linux x64.

This issue appeared after version 4.1.0 (9/19/2019) of the DevTools Chrome extension.

Might be same bug as #16843 but this one appears without any complicated reproduction steps.
