Fix initializing OrgNode level to string to parse org files

- Parsed `level` argument passed to OrgNode during init is expected to
  be a string, not an integer
- This was resulting in app failure only when parsing org files with
  no headings, like in issue #83, as level is set to string of `*`s
  the moment a heading is found in the current file
