Make the device id on e2e key upload optional
We should now be able to get our device_id from the access_token, so the device_id on the upload request is optional. Where it is supplied, we should check that it matches. For active access_tokens without an associated device_id, we ought to register the device in the devices table. Also update the table on upgrade so that all of the existing e2e keys are associated with real devices.
