dev: initialize chain-id after upgrade (#1631)

Initializes the chain_id after upgrading kakarot if it's unset
Fixes an issue where eth_send_transaction would use the `eth_chain_id()`
of the network instead of the one that is defined in the constants,
leading to tests passing even though the onchain `chain_id` was not
correct

Closes #1629
