As soon as dx-core was updated to latest TF 1.3-SNAPSHOT publication workflow tests started to fail, apparently getting stuck when logging out and try to login again with a different user at LoginPage#exists (see PublicationWorkflowFunctionalTests_publishSingleNestedPage.mp4).
Debugging showed that the following Selenide error was thrown (but not displayed in logs)

No webdriver is bound to current thread. You need to call open(url) first.

Reverting the changes done with this commit gets rid of the issue but of course it's best if we figure out how to do it without using WebDriver directly.
