Unable to decline / delete proof request if contact no longer exists

[bryce-mcmath]

Description of problem

If the app gets into a state where a contact is removed / no longer exists but the user still has a proof request from said contact, the proof can no longer be declined, it just triggers an error and exists somewhat permanently in the notification list on the home screen. Haven't found a reproducible way to get into such a state but I can confirm it's possible.

Expected behavior

@knguyenBC should the user be able to delete contacts who have active proof requests? If such a contact is deleted, should all their associated proofs be deleted as well? Should proofs that are orphaned like this not show up in notifications?
