edit: Don't reprint edited object when done with it

Interactive edit prints the edited object, then reads player input.
If it gets key and value, it applies them to the object, and repeats.
If it gets nothing, it prints the edited object again, and stops.

Remove this last print, because it's not really useful.  The object is
commonly the same after reading input as before.  Except when a nation
gets updated while "edit c" is waiting for input: then the second
print actually reflects the updates.  Has always been that way.
