Matt Ellis cad1949dba Fix an issue updating a newly created stack from the local backend
When creating a new stack using the local backend, the default
checkpoint has no deployment. That means there's a nil snapshot
created, which means our strategy of using the base snapshot's secrets
manager was not going to work. Trying to do so would result in a panic
because the baseSnapshot is nil in this case.

Using the secrets manager we are going to use to persist the snapshot
is a better idea anyhow, as that's what's actually going to be burned
into the deployment when we serialize the snapshot, so let's use that
instead.
