Hello, 
when I send an invitation to attendees of event, they recieve an invitation and they see nice choice [accept][decline], but when they switch to empty folder, the message is still visible.

Reproducible: Always

Steps to Reproduce:
-1. get Event invitation create a new task and put your email address as attendee and send it.
0. recive Event invitation
1. click on Event invitation mail, you can see "This message contains an invitation to an event [Accept][Decline]" above mail
2. click on empty folder
3. "This message contains an invitation to an event [Accept][Decline]" is still shown where email message normally is (in empty folder is of course not)


Expected Results:  
The "This message contains an invitation to an event [Accept][Decline]" should not be seen.
