Summary0011821: wallets should show notifications when balance changes due to double spending
DescriptionWhen a wallet restored from a backup contains coins already spent, a payment can cause an unexpected balance jump: The balance decreases due to the completed payment *and* due to detected double-spending.

In this case, we should display some kind of notification to the user.

Alternatives would be separate transactions for double spending, but IMO dismissable notifications are better suited:
* These events don't fit the typical transaction lifecycle
* It doesn't make sense to merge them in backup/sync
