emacs: hello: bugfix: make alphabetically sorted saved searches work

My recent changes to the saved search format broke the alphabetically
sorted saved sort option. This makes it work again.

Also update docs for saved-search sort defcustom to match the new
format.

Finally, since the saved-search list is no longer an alist change the
names in the sort function to avoid confusion.
