When there is a Calendar added to a page and edit some event to decline it, the Event will disappear after being declined until refresh Calendar's page.

  Steps to Reproduce in master/7.0.x:

1. Start a portal bundle and login with admin roles.
2. Create a new page
3. Add a Calendar app
4. Create a new event:
   • Click on some day into the calendar (a modal window will appear).
   • Click on save button.
5. Click on new event created in last step (a modal window will appear).
6. Click on 'View Details' button (other modal window will appear).
7. Click on 'Decline' button and Close current modal window.

Current behavior:
Event declined has disappeared.

Expected behavior:
Event does not disappear, and it is showed with "text-decoration: line-through;", I mean, using strikethrough text.
