Ticket 47311 - segfault in db2ldif(trigger by a cleanallruv task)
    
    Bug Description: If you run db2ldif while the server is stopped, and there is
                     an unfinshed cleanAllRUV task, when the task finishes it tries
                     to trim the changelog, but the changelog has been initialized
                     yet.  This leads to a crash when trying to trigger the trimming.
    
    Fix Description: Do not resume incomplete cleanAllRUV tasks when running db2ldif.
