[performance] improve wallet update performances

`wallet-autoconfig-token` is a very expensive call on mainnet
because it checks the balance of every known token.

it is called:
- when wallet is refreshed by pulling
- when user goes on any wallet screen

this PR changes that by:
- calling it only when the wallet is initialized and there is no
visible-token configuration

it only calls update-wallet when a new transaction arrives
