tdf#163948: fix crash when NotesPane is enabled on Tabbed UI

Pane shells (BottomImpressPane, LeftImpressPane etc.) do not implement any slot
handling, so make sure they are not activated on the top of the shellstack.

Another solution for this could have been getting ChildWindowPanes properly
dispose instead of Hide() at BasicPaneFactory::releaseResource, and adapting the
rest of the code which assumes these Panes are recycled.

This is since ConfigurationUpdater::UpdateCore attempts at releasing via
ConfigurationUpdater::CheckPureAnchors and
ConfigurationControllerResourceManager::DeactivateResources calls.

But in the end the ChildWindowPane is hidden on the DeactivateResource call
instead of being diposed, so the "PureAnchor"'s Shell stays at the shellstack.
