    Ticket 48445: keep alive entries can break replication
    Bug Description:
    	On the consumer side, at the end of a total update the replica is enabled and the changelog recreated.
    	When the replica is enabled the keep alive entry (for that replica) is created .
    	There is a race condition (that look quite systematic in our tests) if the creation of the entry is added to the changelog
    	before the changelog is recreated.
    	In that case the ADD is erased from the CL and will never be replicated.
    	The keep alive entry is created (if it does not already exist) :
    		- during a total update (as supplier)
    		- when the keep alive is updated
    		- when the replica is enabled
    Fix Description:
    	It is not strictly necessary to create the keep alive when the replica is enabled.
    	So we can skip the creation during that step.
