ui_tests: fixes for issues with sending key and focus on element
Fixes 2 issues in WebUI tests. One issue is that we are unable to
confirm a dialog by "Enter" keyboard - "actions.click()" helps
here to get focus on the page.
Second issue is probbaly related to screen resolution as we cannot
click to some of the action buttons (buttons which are having issue
varies).
