Bug: null value logs as undefined

[dever23b]

Describe the bug
TSLog writes null values as undefined. It severely threw off my troubleshooting of an unrelated bug in my project.

To Reproduce
Steps to reproduce the behavior:

const testObj = { true: true, false: false, null: null, undefined: undefined };
console.debug('Testing [console]', testObj);
log.debug('Testing [tslog]', testObj);

Testing [console] {true: true, false: false, null: null, undefined: undefined}
index.js:81 2023-07-09 05:09:32.911 DEBUG TestComponent Testing [tslog] {
true: true,
false: false,
null: undefined,
undefined: undefined
}

Expected behavior
Correct values to be displayed when an object is logged

Works in V.4.8.7

Ran into same problem in 4.9.1.
Wasted quite a bit of time debugging an issue that I didn't have in the first place.
Please include a null check in the tests 🙏

That's also how I discovered the bug too, unfortunately.

Looks like it's only happening in the browser because of a polyfill. Opened a pull request with a fix and additional tests.

Thank you. I'll check and merge it tomorrow.
