  dialog: fix incorrectly discarded dialogs after sync

Syncing while the donor node is also sending live replication packets
may lead to incorrectly discarding some of the newly received dialogs.
There were two ways in which new dialogs were actually mistaken as old,
"local" dialogs from before syncing:
* overwriting the dialog flags when handling a replicated update;
* not marking live replicated dialogs received during sync as "new" dialogs.
