Fix todo-mode category movement

Browse source 
* lisp/calendar/todo-mode.el (todo-move-category): Use moved
category's existing categories sexp instead of invoking
todo-update-categories-sexp in file moved to, in order to take
archived items into account.  If the moved category has archived
items, handle the source archive buffer properly.  Remove
superfluous code.
