Potential issue when updating from non-deterministic subwallet -> to deterministic

[f-r00t]

Some users have been complaining about issues with sending messages when updating from 1.3.0 > 1.3.1. Potenitally this is because of the update to deterministic wallets. Additional information is required.

I think the problem is here: https://github.com/kryptokrona/hugin-mobile/blob/master/src/HuginUtilities.js#L390

Due to some "old" users still have the old subwallet as no. 2, you will need to enforce a blank second address and instead use no. 3 as your new "messageSubwallet" like this : let [mainWallet, subWallet, messageSubWallet] = js_wallet.subWallets.getAddresses()

Check this https://github.com/kryptokrona/hugin-desktop/blob/main/src/backend/electron.cjs#L1431

It creates a blank second address and creates the deterministic messageSubwallet aswell. Seems to work for me
