chain: statestore needs to include accounts or drop accounts?

[VandeurenGlenn]

Whenever a node connects it will try to update from the state store, meaning accounts should be in the state also or empty nodes will fail getting the account nonce

Solutions

• drop accounts (easy but means no easy way to check for total transfers)
• rewrite accounts so that when a state is saved we include the accounts in state and clear the local accountsstore.
