Bug at reorgs

[chimp1984]

When a reorg happens the app gets in a loop of deleting daoState to get it replaced from resources and requesting new blocks which triggers the cycle again...

I will look into fixing it after the open PRs are merged.
Simple version would be to enforce a restart. Other more complex option is to replace daoState with resources without restart. But that might cause issues in clients if they do not listen to that event and not getting updated.
Not sure how often reorgs happen in Bitcoin, I guess very rarely. If so the restart options seems ok and carries less risk.
