(ITS#6807) syncrepl sends incomplete sync cookie in MMR

In syncrepl_updateCookie() the cookie received from the provider is dup'd as-is. If the provider is stopped and restarted, this same cookie will be sent back on the next refresh attempt. In refreshAndPersist mode the cookies sent from the provider will only contain a single CSN; CSNs from other MMR servers are omitted. During a restart, because the consumer sends a cookie with only one CSN, the provider will consider the consumer out of date.

A fix is coming shortly.
