Issue 1370 - Update change username confirmation message to something more informative, and update tests to match.
Add a step for visiting the change username page, so that we don't repeat the navigation steps on every scenario.
Break apart the change username tests so that they are each testing one thing.
Add a confirmation message (with a translation string) to the submit button for Change Username.
User name should be two words in messages to users.
