fix(_uploadExisting): fix function update errors

Immediately after updating the settings, `Configuration.LastUpdateStatus` is `InProgress`.
If you update the code in that state, you will get an error.
You need to update the code after the `Configuration.LastUpdateStatus` becomes `Successful`.

I've fixed it to wait until it becomes `Successful`.
