Show indicator when client setup fails (#339)

Summary:
At the moment, when a client is failing to connect, you effectively get an infinite spinner, as it keeps retrying.

This keeps the spinner while it's retrying, but in between, shows a failure icon.

This isn't perfect. It's still shown under possibly the wrong device, but that already happens anyway, this just adds an extra icon.
