LUCENE-10190: Ensure changes are visible before advancing seqno (#640)
DocumentWriter#anyChanges() can return false after we process and
generate a sequence number for an update operation; but before we adjust
the numDocsInRAM. In this window of time, refreshes are noop, although
the maxCompletedSequenceNumber has advanced.
