Anton Kaliaev 5b1b1ea58a [libs/autofile] fix DATA RACE by removing openFile() call (#2539)
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
