Fix KeyError in config flow of Bring integration

[tr4nt0r]

Proposed change

Type of change

This fixes a possible KeyError during setup, which happens if the user has registered with Bring through the browser application. In the mobile apps the username is a field that can be omitted, but the API still returns an empty string. In the web application it is not possible to set the username and the API doesn't include this parameter in the JSON response until the user connects to Bring with the mobile app for the first time.
