Reading the Nonce from the local cache may be incorrect if the tx is made out of the Status app or
if Status app sends a tx prepared by the dapp (via WalletConnect). A submitted tx with a wrong Nonce
results in a failing tx, that's why we need to read the Nonce from the network.
This functionality is needed in case the user wants to send a transaction and
signs it using the signature provided by the keycard (or any other compatible way).
