Summary:
This test currently uses `jest.runAllTicks()` to execute cached, immediately-resolving promises, under Jest "legacy" timers (the RN default) - this works only because [we polyfill Promise](https://github.com/facebook/react-native/blob/main/jest/setup.js#L24) using a userland JavaScript implementation that internally uses mocked-out timer functions.
Here we change to a more universal approach by adding a new microtask/promise to the end of the queue and awaiting it.
This allows us to remove our Promise polyfill from Jest setup (to follow).
Changelog:
[Internal][Fixed] - Prepare `LogBoxLog-test.js` for native promises
