Correctly restore view config of all split views
Review Request #128163 - Created June 12, 2016 and submitted
KateViewManager::createView() only sets the activeView, if there is no active view yet. Therefore, prior to this patch, viewManager()->activeView() returns always the same view. Consequently, restoring the view config always used the same view, which of course does not properly work.
Compiles, works. manually tested.
