core/state: mark account as dirty when resetObject occurs (#27339)

Browse Source 
This changes the journal logic to mark the state object dirty immediately when it
is reset. 

We're mostly adding this change to appease the fuzzer. Marking it dirty immediately
makes no difference in practice because accounts will always be modified by EVM
right after creation.
