Rollback in dev mode is not working

[davidyuk]

It was mentioned in other issues, but I think better to have a separate one.

I'm running mdw in dev mode locally. I've sent 100ae an account, then called http://localhost:3313/rollback?height=0. I expect the balance to be zero, but http://localhost:3013/v3/accounts/ak_8eAGBq1jP4dLsmnmgnSzRBxSh5SU1AVsgbCwSQcXZVwwB6c1t still returns 100ae.

I think this feature can be implemented in a hacky way, usually dev mode chains are not very long. So maybe middleware can drop its database and sync with the node again if /rollback is called?

Configuration I'm using docker-compose.yml
