fix: repair refile to headline in the same file (#633) (#637)

* fix: repair refile to headline in the same file

- use correct line position from target headline
- reset cursor back

* chore: apply requested change (#637)

Use vim.fn.winsaveview/winrestview instead of manually caching the
cursor position when refiling within the same file.
