Some dialog consistency work:

* Dialog::updateData(): try to reset the dialog even if there's no Buffer.
* GuiView::updateBufferDependent():
- renamed to updateDialogs()
- don't hide when there's no current work area, try to disable instead.
- now also take care of toolbars and other elements. 
* TocWidget: delay item selection to avoid unwanted node collapsing after setting a new model.

Expect crash and/or assertions for dialogs that are not ready for this non-hiding change. I will fix them iteratively.
There are still too many dialogs updates going on...
