fill -v tests/amsterdam/eip7708_eth_transfer_logs/test_transfer_logs.py::test_selfdestruct_to_self_cross_tx_no_log --fork Amsterdam

Test that selfdestruct-to-self in a cross-tx context emits no log.

A contract created in Tx1 is not in created_accounts during Tx2. Selfdestruct-to-self in Tx2 emits no log per EIP-7708: no Burn log (not same-tx) and no Transfer log (not a different account).

Contract creation tx (to=None) deploying SELFDESTRUCT(ADDRESS),

value=2000. Logs: [transfer_log(sender, created, 2000)]

Tx2: Call created contract directly, value=0. Logs: [] Post: contract keeps balance (not deleted, not in created_accounts in Tx2)
