When the master's log has all entries from version 1 to now, and no uber entry (legacy master), then new slaves will not pull version 1, because their uber record has version 1. The fix is to force the uber version to 0 always, and avoid adding a truncate nop when doing a full prop. The uber record now records the database version even in the absence of any other log entries so that we know what to pull going forward.
