Update JSON tests to d4f86ecf4aa7c (#11054)

* new ethereum consensus tests, #10908

* Update JSON tests to 725dbc73a

This PR reverts the controversial changes of the previous PR and skips the failing tests.

Maybe I misunderstand the suggested workaround of putting the fix under `#[cfg(test)]` but it seems odd to run different code in production than we run in tests. Instead here I suggest we skip the failing tests with the argument that we do not wish to fix this issue (at least not at this time) because it does not affect us. If I am wrong, and I likely am, I look forward to hearing why and what a better approach to updating the state tests is.

Branched off #10923

ref #10908
