Fix race in `MultiWriterIdGenerator` (#11045)
The race allowed the current position to advance too far when stream IDs are still being persisted. This happened when it received a new stream ID from a remote write between a new stream ID being allocated and it being added to the set of unpersisted stream IDs. Fixes #9424.
