fix ImportMailState CREATE event not downloading imported mails

After importing mails on the desktop client, those mails are not visible
immediately on other devices with offline storage. This is due to the
optimization of EntityEvents (CREATE + UPDATE = CREATE). Previously, the
mails were only downloaded on ImportMailState UPDATE events in the
MailViewModel, which are never processed on the devices not making the
import. This led to a corrupted state where the imported mails are never
downloaded to the device. This fix ensures that the mails are downloaded
and the offline storage is updated properly.
