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.
