component AP gateway: ignore actor delection notifications: When a `Delete` activity was received and the object was the emitting actor itself, the signature checking was failing if the actor was unknown (due to the impossibility to retrieve the actor public key, as it is no more accessible). To avoid that, those notifications are ignored for now. In the future they should clean the cache linked to this actor.
