    Cleanup chunks for deleted image if token expired

    In patch I47229b366c25367ec1bd48aec684e0880f3dfe60 it was
    introduced the logic that if image was deleted during file
    upload when we want to update image status from 'saving'
    to 'active' it's expected to get Duplicate error and delete
    stale chunks after that. But if user's token is expired
    there will be Unathorized exception and chunks will stay
    in store and clog it.
    And when, the upload operation for such an image is
    completed the operator configured quota can be exceeded.

    This patch fixes the issue of left over chunks for an image
    which was deleted from saving status, by correcly handle
    auth exceptions from registry server.
