Scott Nonnenberg 8c85f6e3a6 When marking message read, ensure that peers have same read_at
When we mark a message as read, we go to the database to ensure that
older messages in this conversation are marked read as well. That
optimization was missing the read_at value provided to the starting
message, so now it is piped along to all of them.
