cli/reply: do not parse Reply-To: header into internet address list twice

Browse source 
Avoid parsing Reply-To: header into internet address list twice. Move
the parsing outside of reply_to_header_is_redundant(), and pass the
parsed internet address list in as parameter. This also avoids leaking
the memory of one copy of the internet address list.
