Don't select nodes inserted by a dialog, but drop cursor after

It used to be that when you closed a dialog, the thing that the dialog
inspected or inserted would be selected. For insertions, the selection
will now be collapsed immediately after the inserted node.
For modifications, the original behavior was kept, as it makes sense to
keep selecting the node that the user had to select in order to access
the dialog. For removals (only possible in the transclusion dialog),
the selection ends up as a collapsed selection at the location where
the removed node used to be; this was already behaving correctly,
as we get this behavior for free with offset translation.
