test_field_as_list()

Documentation for tests/frontier/validation/test_transaction_rlp.py::test_field_as_list@49633827.

Generate fixtures for these test cases for Amsterdam with:

fill -v tests/frontier/validation/test_transaction_rlp.py::test_field_as_list --fork Amsterdam

Encode one field as an RLP list instead of a byte string.

The gas price and v fields are equally rejected but have no field-specific decoding exception, so they are not covered.
