This PR prevents errors caused by
nullaccount balances. This problem is described in detail #5842While we need to resolve the root cause of that as soon as possible, this PR provides a front end band-aid by saving the most non-null balance for each account in local storage. If the account balance is null when we select it from state, we will instead return the most recent cached value.
These null returns are very inconsistent and almost never happen two blocks in a row, so the account balance will (almost always) be at most one block out of date.
