It should be the same delivery code, but just in case I added also "lmtp / with sieve fileinto box" test and it passes as well.

This is with lmtp if it matters.

I added a bunch of tests for lda_mailbox_autocreate and lda_mailbox_autosubscribe and they seem to work fine:

 * dovecot-lda -m box / without sieve
 * dovecot-lda -m box / with sieve keep
 * dovecot-lda / with sieve fileinto box
 * dovecot-lda / with sieve fileinto :create box

So, I can't reproduce any bugs related to this.
