"Failed to record url fail record": ENOENT

Describe the bug

When an error occurs fetching a feed, the bot logs an error message trying to record the error.

To Reproduce

Running in Docker, latest version:

$ docker run --restart unless-stopped \
  -e 'DRSS_DATABASE_URI=/data' \
  -e 'DRSS_BOT_TOKEN=red.act.ed' \
  -d -v /var/local/Discord.RSS:/data \
  --name discord-rss synzen/monitorss

Add a feed entry which would fail to fetch (e.g. 403)
Notice an error message in container logs

Expected behavior

No error log in container and error structurally logged to fail_records directory (in fact it exists but is empty).

Branch

Docker latest.
