See #4202 for context. Apparently some third-party systems don't use the primary cache key that's used for cache restores as a restore key if it's not also included separately as a restore key. This PR changes our restoreCache calls so that the primary restore key is also always included as a restore key. This should not make a difference on first-party systems.
