lda: Do not replace the NULL sender with a default <MAILER-DAEMON> address.

Only do this substitution locally where a NULL sender would cause problems, not everywhere else.
This e.g. causes problems when determining whether to send a rejection somewhere; attempts would be made to mail <MAILER-DAEMON>.
Also other envelope-based (Sieve) tests would get confused.
