    Ticket - 49623-cont cenotaph errors on modrdn operations
    
    Bug: In modrdn operations a cenotaph entries are created to track the time when
    	an entry had existed. But in cases where rentries were renamed in cycles
    	reusing the dns again and again this failed with an error: "faild to add cenotaph"
    
    Fix: Previous versions of cenotaphs with the same dn are not used (or maybe in very unlikely
    	scenarios) so there is no need to change the dn construction to be able to keep all
    	versions of the same cenotaph. Instead, if the creation of the cenotaph fails because
    	it already exists, the existin cenotaph is moodified with the lifespan data of the
    	cenotaph that was tried to add.
