This happens with Copy&Paste:
1) Create a note
2) Collapse it
3) Place the mouse cursor over the inset button.
4) Select the inset with the keyboard
5) type Ctrl-v immediately followed by Ctrl-v. The note inset is then
replaced by its own copy.
6) move the inset out of the inset
I find a simple solution to this: reset last_inset_ for each update.
Since I do not imagine any bad side effect of this change, I have
committed the change.
