IMAP test for imap_rfc822_parse_headers() does not test function

[Girgias]

Description

Found while working on: php/doc-en#163

See: https://github.com/php/php-src/blob/8995f602584a5267999f51cbc73f8c03eee36074/ext/imap/tests/imap_rfc822_parse_headers_basic.phpt

But except if I'm completely missing something, we don't have any test coverage for imap_rfc822_parse_headers() which is slightly concerning.

There seems to be some coverage for this.

ext/imap is being unbundled so closing this.
