Bugfix: ratelimit set in bootstrap (#162)

- If a ratelimit was not specified in the request and the client existed, its current ratelimit gets overridden by the default ratelimit
- If a ratelimit was specified in the request and the client existed, its ratelimit is changed without verifying it has the required quota to do so
