Update token info cache in tx history
I thought this wouldn't be necessary because the token info cache is updated by utxos immediately before tx history is called. However, I fortunately discovered an edge case. You can have a situation where
1. Cashtab user in Cashtab wallet Alpha in browser Alpha receives eToken Alpha
2. Cashtab user in Cashtab wallet Alpha in browser Alpha burns eToken Alpha or sends it away
3. Cashtab user opens Cashtab wallet Alpha in browser Beta. Now that etoken is not in the wallet utxos nor is it in cache of browser Beta. But it's in the tx history. If this isn't handled, it will never be added to cache, and the tx history will not have token decimals, so it will be rendered incorrectly.
This diff uses a similar approach to that used in the chronik utxo implementation.
