The split view function duplicates the current view instead of opening a new one.

Reproducible: Always

Steps to Reproduce:
1. Open Konsole
2. Split the view
3. Open new tab in one of the views

Actual Results:  
The second view is a duplicate of the first one.
The new tab opens in both views.

Expected Results:  
The separate view should open a new separate terminal.
Adding a tab should open a new terminal, not duplicate it.

If duplication is desired, then a button called "Duplicate view" should exist.

Desired effect can be achieved like this:
1. Open 3 (separate) konsole instances (3 separate windows)
2. Split the view in one of the konsoles
3. Drag the tabs of the other 2 in the splitted one, each in a different split
4. Close the duplicated konsole (tab)

Problem with this: When all tabs in a split view are closed, you are left with a blank split.
Closing the last split, should exit that split view mode.

Hints: Look at how the Terminator terminal works. Konsole does this better by also having tabs and the ability to drag tabs into separate windows.
