'Finish Setup' button for provisioned devices is confusing

### Current Behavior

https://d.pr/v/YonFBZ

When setting up several devices using a provisioning token I keep seeing a button which says 'Finish Setup' but after a few seconds that button vanishes. This gave me the impression that I had missed a setup step.

### Expected Behavior

An alert button like that should not appear unless a user actually needs to take action.

### Steps To Reproduce

### Environment
