Scenario: I change my password
    ✔  Given I sign in as a user                        # features/steps/shared/authentication.rb:7
    ✔  Given I visit profile password page              # features/steps/shared/paths.rb:102
    ✔  Then I change my password                        # features/steps/profile/profile.rb:68
    ✘  And I should be redirected to sign in page       # features/steps/shared/authentication.rb:23
