    Ignore stale image property removal

    Occasionally we fail to delete a property from an image and get a
    StaleDataError from SQLAlchemy. It looks like maybe we are just racing
    with another operation to delete a single property (i.e. a race
    between image delete and the end of an import cleanup).

    This ignores that "can't delete because it is already deleted" error
    and logs to debug about the situation for later auditing and
    confirmation.
