Bug fix: In simulation, KVStoreSQLite can outlive its process during a simulated reboot so its file references must be cleared explicitly during shutdown instead of implicitly during destruction. Re-enabled a useful trace event. Some cleanup, removed unnecessary member var initializer and removed unnecessary method.
