There's a time window after we call RotateFile() where autofile#index+1 does not exist. It will be created during the next call to Write(). BUT if somebody calls NewReader() before Write(), it will fail with "open /tmp/wal#index+1/wal: no such file or directory" We must create file (either by calling gr.Head.openFile() or directly) during NewReader() to ensure read calls succeed. Closes #2538
