This issue has been migrated from #13783.

While writing matrix-org/complement#459, it was noticed that Synapse would sometimes emit an unnecessary device_lists.changed entry in the next sync after retrieving the device list for a remote user.

While it doesn't contravene the spirit of the spec, it's inefficient as well-behaved clients will ask the homeserver for device keys a second time.
