Fixes the first run messages

no issue

- Whilst testing the mail PR #3915 I noticed the first run messages aren't
  appearing because the dbHash is getting pre-populated, but there doesn't
  appear to be a reason why this is necessary
I don't think this is a timing error - there's no sign of the notification in any test at all on travis and yet they work instantly locally. Going to look into a different way to test.
