[WC v1] Fixed signTypedData_v4 routing

[justindg]

• Closes Issue signing off-chain transactions with wallet-connect #3139
• Closes Unable to initiate a transaction in polygon in Dapp browser and/or WalletConnect #3087

eth_signTypedData_v4 messages are not routed properly because of a missing enum, hence the signing dialog does not appear.

Do we also need a route for eth_signTypedData_v3 ?
