Handling of incoming typing stream updates from replication was not hooked up on master, effecting set ups where typing was handled on a different worker. This is really only a problem if the master process is also handling sync requests, which is unlikely for those that are at the stage of moving typing off. The other observable effect is that if a worker restarts or a replication connect drops then the typing worker will issue a `POSITION typing`, triggering master process to try and stream *all* typing updates from position 0. Fixes #7907
