I need to confirm this, but I think it's more of an issue of the time between sign ins, not sign out and sign in, which is why the test in Moztrap passed some of the time. Whether or not the remember me screen will appear will then depend on how long the steps of the test take to complete, which is why we cannot really have a valid expect.  

I don't love the sleep logic either, but I also don't think adding another expect really addresses the issue, which is that clients of bidpom shouldn't have to know how much time has elapsed bewteen logins in order to know what to expect. Clients should be able ti simply say the user is returning and bidpom should be able to deal with the screen-sometimes-appearing issue.
