Test missing basefee

In this test, the currentBaseFee is missing from the env portion. On a live blockchain, the basefee is present in the header, and verified as part of header validation.

In evm t8n, we don't have blocks, so it needs to be added in the envinstead.

When it's missing, an error is expected.
