[Gelbooru] Failing to download from Gelbooru favorites page when having a certain number of favorites

[Phultin]

When looking at your favorites on Gelbooru through your account, each page of favorites has at most 50 images. New favorites are put on page 1, and the oldest favorites are pushed back, with new pages being made as necessary. However, when the last page of favorites has 27 images, a new, blank page will be created. Trying to download your favorites list while this blank page exists will result in an error "tuple object has no attribute 'reverse'". This blank page will persist until you add enough new favorites to fill up the second-to-last page with 50 images, then add 1 more so that the last page is no longer blank.
