Summary: I added this check [a couple of years ago](https://github.com/facebook/react-native/commit/1b22d49ae8945680dee4fd01e3fbb78b1e443e01) to mimic how [React used to check for async roots](https://github.com/facebook/react/blob/acabf112454e5545205da013266d8529599a2a82/packages/react-reconciler/src/ReactFiberReconciler.js#L321-L330). This code doesn't make sense anymore since there's neither an async base class or an `unstable_ConcurrentMode` export, so I'm just cleaning it up.
