Deleted this because they depend on legacy context, they still exist in ReactDOMLegacyFiber

Note: the old console.error
only existed in the legacy root, the new root only throws.

This is weird to me, it looks like we don't error when you do an update to a component that was manually updated (see this test and the one below it). It just silently keeps the content that was replaced in the DOM.
We do error if we do a replacement though (see test above).
Is this a bug @acdlite?

Deleted legacy only test, new roots can't be updated after they're unmounted, which we have tests elsewhere for. Still exists in ReactDOMLegacyFiber

Walked through this one with Rick. Missing errors with createRoot are concerning but seems ok to land this migration work that represents the current behavior and follow up with fix on the error messaging if needed.
