solidusio/solidus_auth_devise#225

Scenario: I should be able to reload the app after changing a user
decorator

Given I am logged in
When I go to the the account page
Then I should see the value of UserDecorator#decoration
When I change the value the UserDecorator#decoration
And I refresh the account page
Then I should see the new value
