[PATCH v4 04/17] fix: utils: Fix the extract_list() utility function

[Muhammad Rizki <kiizuha@gnuweeb.org>]

Fix the extract_list() when the `payload.get()` header function is not
retrieving the header value instead of throwing error.

Simple error log says:
AttributeError: 'Group' object has no attribute 'local_part'

Source problem: https://s.id/1n1C6 (shorted lore email URL)
