Unsubscribe buttons on 'My calendar' do not unsubscribe

[gosko]

When I view my personal calendar using the 'My calendar' link in the user menu, each upcoming event has a button underneath that says 'Unsubscribe from this event'. Clicking the button does not actually unsubscribe, it just links to the event where you need to click the same button again to unsubscribe. The button styling on the 'My calendar' view makes it seem like it will actually unsub, not just link to the event page. I think that button should either be removed from the 'My calendar' view, be restyled, or have its text updated to something like 'View this event' or 'View this event to unsubscribe'
