LiveQuery publishes user session tokens in parse-server
### Impact
For regular (non-LiveQuery) queries, the session token is removed from the response, but for LiveQuery payloads it is currently not. If a user has a LiveQuery subscription on the `Parse.User` class, all session tokens created during user sign-ups will be broadcast as part of the LiveQuery payload.
### Patches
Remove session token from LiveQuery payload.
### Workaround
Set `user.acl(new Parse.ACL())` in a beforeSave trigger to make the user private already on sign-up.
