test_failed_create_with_value_no_log()

Documentation for tests/amsterdam/eip7708_eth_transfer_logs/test_transfer_logs.py::test_failed_create_with_value_no_log@5c024cbb.

Generate fixtures for these test cases for Amsterdam with:

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

Test that failed CREATE with value does NOT emit transfer log.

When initcode fails (REVERT, INVALID), the value transfer is reverted and no log should be emitted for the CREATE.
