bug#38614: 26.3; Info completions in reverse order

[Howard Melman]

When using ivy mode, Info-index shows me the list of
completions in reverse alphabetical order. Info-menu does too.
Both Info-index and Info-menu use completing-read with
Info-complete-menu-item as the collections argument. It
seems to generate the list in reverse order.

Sorry this isn't a formatted patch, but a one line fix solves it for me.

If after this line in Info-complete-menu-item:
                    (setq completions (delete-dups completions))
I add this line:
                    (setq completions (nreverse completions))
the index and menus are shown in alphabetical order.

Howard
