Update client.UnreceivedEntityEventCount on every event write

I noticed that if the main event IDs went over 10000 and there were more than 450 unique events, the server would sometimes skip the next event the client needed. Sometimes the client would also not realize that the last event it received was the final init event, so it would reject all further events because of a huge ID discrepancy. The init events will likely need to be reworked, but updating UnreceivedEntityEventCount seems to help somewhat.
