When we indicate that a getncchanges request is not complete, we set
the more_data flag to true in the response. The client usually then
asks for the next block of data. If the client decides it wants to
skip that replication and do a different replication then we need to
make sure that the next call is in fact a continuation of the existing
call, and not a new call.
This relies on returning the results sorted by uSNChanged, as the
client uses the tmp_highest_usn in each result to see if progress is
being made.
