c73774467e
When a remote user leaves the last room shared with the homeserver, we have to mark their device list as unsubscribed, otherwise we would hold on to a stale device list in our cache. Crucially, the device list would remain cached even after the remote user rejoined the room, which could lead to E2EE failures until the next change to the remote user's device list. Fixes #13651.
