Same problem here. As a workaround I tried the following:

# From Spam folder to Inbox
  imapsieve_mailbox2_name = Inbox
  imapsieve_mailbox2_from = Spam
  imapsieve_mailbox2_causes = COPY
  imapsieve_mailbox2_before = file:/usr/lib/dovecot/sieve/report-ham.sieve

In theory this should trigger the  report-ham script, only if a mail is
moved from Spam to Inbox. However, it does not seem to work either.
