Ticket 51260 - fix potential syncrepl data corruption
Bug Description: The cookie encodes which changelog entries we
have seen up to and including. However, the sync process would then
re-send the cl item from the cookie number. This could cause corruption
in some cases as some combinations of actions between two points
are no-oped in the server.
Fix Description: Fix the changelog search to always process that
entries of the CL must be greater than, but not equal to the
already seen CL items from the cookie.
