Storage: Add siteID parameter to stats queries

[ealeksandrov]

Description

Due to missing siteID parameter in StorageType+Extensions for stats related objects, we are ignoring multi-store support and overwriting data between stores.

It doesn't result in any user-facing errors, since we're overwriting siteID as well, so it's just unnecessary removal of the data from unrelated store.
