[0/2] refs/files-backend: fix two subtle error-handling bugs

This series fixes two bugs around the error-handling of writing
packed-refs during ref deletion. The first one came from a real-world
case.  The second is impossible to trigger (currently), but since I
noticed it while hunting the first one, I figured it was worth fixing.

  [1/2]: refs/files-backend: handle packed transaction prepare failure
  [2/2]: refs/files-backend: don't look at an aborted transaction
