Start empty when the cache directory holds another account's cache (closes #104)

 A stored file appears only via an atomic temp-then-rename, so its presence means
 it is complete. The design also calls for a content-hash comparison against
 `FileMetadata.hash` on each fetched original; that check is deferred (issue
