Ticket #47801 - RHDS keeps on logging write_changelog_and_ruv: failed to update RUV for unknown
    
    Description: When no operation is given to write_changelog_and_ruv
    (consumer has the chance just to update ruv) and opcsn is NULL,
    update_ruv_component immediately returns the default return value
    RUV_NOTFOUND, which should not be logged as SLAPI_LOG_FATAL but
    just ignored.
