Sort order for alphabetical page sorting is reversed

[unmacaque]

I have noticed that pages are sorted in reverse alphabetical order when alphabetical sorting is configured.

To reproduce:

• Download latest Raneto version (0.17.6), install and start
• Open config/config.js and set page_sort_meta to an empty string '', which according to docs should sort pages alphabetically
• Restart Raneto
• Pages are now sorted in reverse alphabetical order

With version 0.17.3, the sorting order is as expected so this appears to be introduced after this version.

In case it helps, I did a bisect and be11e5f29d4d430985c84b91107b6b5e7e53e1f4 is when this got first introduced.
