Fix bug reporter failing after not finding some files (#1103)

- Make sure we propagate `CancellationException`.
- Make sure we do a cleanup of temp files.
- Make sure we don't re-compress any lingering temp files.
- Don't stop the upload process if we were able to upload some log files, even if we failed to read some others.
