Remove implicit dependency on `gitlab_sign_in` assigning to a user instance variable

Update carrierwave from 1.0.0 to 1.1.0.

See merge request !12291

We shouldn't be using instance variables in specs to begin with, and
depending on this implicit behavior of `gitlab_sign_in` would have made
it more difficult to change to `sign_in` where possible.

...we've also gone ahead and changed to `sign_in` where possible.

Not sure why this fails with the full login flow, but it's not necessary
and would've been changed eventually anyway, so whatever!

Change `logout_direct` uses to `gitlab_sign_out_direct`

Change single `login_via` use to `gitlab_sign_in_via`

Always use a explicit true/false value to set highlight because jQuery
assumes `null` means toggle from whatever state and doesn't force false.
