    libtracker-miner: Revert deletion of original resource on update
    
    This reverts commit cb0c4c59e60294a455be8f4263dc1fafdc27527c. The real
    bug was in IRI cache invalidation, which is now fixed. File update
    should not trigger a complete resource deletion, it should only delete
    embedded metadata.
