388566 Always publish IUs regardless of the status

- In order to preserve the old behaviour for callers that ignore the
  error status (like the PDE headless build), the created, potentially
  broken IUs need to be written to the metadata repository. This is the
  same as with artifacts, which are also written regardless of the
  status, so I don't see any problems with this behaviour.
