Fixed bug 34668: Cannot tap to Workspace tab after Registration popup appears.

This happened because the registration view extends from isc.Layout, which creates an invisible div at the top of the screen which is not removed when the popup closes, preventing the user to tap in this area.
Now this view extends from isc.Class, same as other views that shows popups from ClassicOBCompatibility.Popup.
