When you subscribe to a collection and then remove that collection, the subscription is still mentioned in the subscriptions tab.

How to reproduce:

• create collection
• add something to it
• subscribe
• remove collection without unsubscribing
• go to subscriptions tab
• it will say that you're still subscribed to it

Expected behaviour

The "1 collection" information shouldn't be there, since the collection has been deleted (impossible to be subscribed to a deleted collection).
