Before this change, if a multisig peer asked you to sign a transaction with a frozen enote, the wallet will do it without any error or warning. This change makes it so that wallets will refuse to sign multisig transactions with frozen enotes. Disclaimer: This PR was generously funded by @LocalMonero.
