`:create` type can fail due to a Bad Instruction in the `init`, but these need to be valid, so we can display the
failures. `to_address_hash` is converted to `t:Explorer.Chain.Hash.t/0`.

Failed `:call`s are not allowed to set `gas_used` or `output` because they are part of the successful `result` object
in the Parity JSONRPC response.
