Remove error snapshot test

I think there is a bug where an empty snapshot is treated as an 'outdated snapshot'.

If I delete the obsolute snapshot, and run ReactDOMFiber-test.js it generates a new snapshot.
But then when I run the test with the newly generated snapshot, it says "1 obsolete snapshot found",
At some point I will file an issue with Jest. For now going to skip the snapshot generation for the error message in the new test.
