fix(anvil): unwrap panic in eth/backend/mem/mod.rs

[zerosnacks]

Motivation

Closes: #11128

Solution

Previously resulted in:

eth_simulateV1
The application panicked (crashed).
Message:  called `Option::unwrap()` on a `None` value
Location: crates/anvil/src/eth/backend/mem/mod.rs:1729

Run with COLORBT_SHOW_HIDDEN=1 environment variable to disable frame filtering.
Aborted (core dumped)

now yields (and no longer panics):

(user side)

{"jsonrpc":"2.0","id":1,"error":{"code":-32602,"message":"Failed to parse transaction request: missing required fields"}}

(anvil side)
