Carlos Garnacho 409f6718b8 calendar: Disconnect all Notification signals on NotificationMessage destruction 
The destroy signal handler is kept connected despite the NotificationMessage
being destroyed, which leaves dangling NotificationMessage objects that will
be mass destroyed when the Notification object these depend upon is finally
destroyed.

Depending on the amount of accumulated NotificationMessages, this may lead
to temporary freezes or other more funky issues when recursion limits are
hit.
