A while ago I optimized Plasma config dialogs to create the component with the cfg_ properties already set. This code relied on the fact that mode changes initially. Use Component.onCompleted now that we can and also use onActivated which only fires if the index is explicitly changed by the user, not on imperative assignment.

Changed sorting to "Name" or "Size", closed dialog, opened it, was still selected. Previously it would always revert to "Unsorted"
