Make all single-fetch database calls return an Option. (#4617)
- Diesel ordinarily throws an error when no results are returned for a
  single fetch, which is a bit confusing. This PR ensures that the
  missing value cases are all caught, and wrapped with new LemmyErrors,
  rather than diesel errors.
- Fixes #4601
