Use the same message if we set a bad login or a bad password.

Hello,

The selenium test https://integration.opensides.be:8080/view/Selenium-Tests-Dev-Jessie/job/Selenium-Tests-Dev-Core/11/testReport/junit/%28root%29/LoginTest/testBadLogin2/ failed because the have another message when we have a bad login.

There is a reason to have two different messages ?

Cheers.
