Pgp signature shows as attachment.
Steps to reproduce:
Compose and send GPG encrypted or signed email.
Result:
Sent email appears in "inbox" and "sent" folders as message with attachment.
Issue:
Treatment of gpg signature as attachment is not informative for the user: the message has no meaningful attachments. Also, attachment filter becomes unusable.
Expected behaviour:
Show attachment icon only if the file was added explicitly by the user.
