Parachain compatibility broken: UnusedProofEntry on token transfer

[bLd75]

During latest tests, we realized smoldot can't make transfer on parachain anymore with the following message:
[tx-service-shibuya] Failed to validate transaction 0xb4f0…bff4: Error in call proof: UnusedProofEntry

The connection is well established with relay (tokyo) and para (shibuya).
Transfers work for any relay chain.
Transfer don't work with parachain.

How to reproduce

• clone the smoldot fork here https://github.com/bLd75/smoldot
• start the wasm-node
• send a token transfer on Shibuya (https://polkadot.js.org/apps/?rpc=ws%3A%2F%2F127.0.0.1%3A9944%2Fshibuya)

Shibuya tokens can be obtained just requesting the faucet here: https://portal.astar.network/shibuya-testnet/assets

I will check it out 👍

For what it's worth, a similar issue was found two months ago (#154) and fixed by paritytech/substrate#13284

If you don't have paritytech/substrate#13284 in, then unfortunately that'd be the cause.

Thanks @tomaka so that may be it, Astar is not yet uplifted to polkadot-v0.9.39 including this fix.
We'll uplift soon and check the issue again as soon as upgrade is made.

For what it's worth, this was a bug in Substrate that happens when you transition the chain to state_version = 1. This is most likely why it used to work in the past but now no longer.

@tomaka I'm closing the issue, para compatibility is back after upgrade to polkadot-v0.9.39, thanks
