Remember me fix

This fixes the scenario where Remember Me wasn't being taken into account when posting a username other than what had been remembered last. (ie, login as test1@test.com with an invalid password but with 'remember me' checked, it wrote the remember me cookie, but if you immediately afterwards login with 'test2@test.com' with a valid password and then log back out again, it is test1@test.com that showed up in the username field as the remembered name. There was a bug filed against this in the client portal.
