core: prevent restoring memory from unsupported version

Add a validation to the preview-snapshot flow that prevents the user from
restoring a snapshot with memory that was taken in a version that is no
longer supported.

While it may be debatable, we choose to block the user from trying to
restore the memory of such a snapshot in order to prevent major problems
in the front-end that are caused by that operation.
