reply: consider the From address too when checking aliases

This sets the likely usually desired From address when replying to a
previously sent email and does not compose To the alias instead (unless
reply-to-self is enabled).

Changelog-fixed: Aliases are now taken into account correctly when
 replying to own messages such as from the Sent folder or via a
 mailing list.
