[BUGFIX] Pasting from a page to another must move parent record

When cutting and pasting elements, the behaviour must be identical
to moving elements with the move command. So it is necessary
to execute the move command on the container before proceeding.

The buggy behaviour was not noticeable as long as the container
was cut & pasted on the same page
