Fixed back navigation on second page

Fixed a bug where the back (newer entries) button didn't show on second page.

Steps to reproduce:

1. Go to loglog page, first page appears
2. Click the "less recent >>" button
3. On the second page, I would expect a button labelled "<< more recent" to return to the first page

Maybe this is somewhat related with the hour advance to trick navigation, but didn't test verbosely. This fix seems to do the trick and doesn't seem to affect other functionalities.
