[BUG] Sorting by rating can not get a stable ordered list

[ivooQ]

Description
When I sort by rating in the marked movie (or books etc.) list like https://neodb.social/users/hyakkei/complete/movie/?sort=rating, the order of the list is not stable. One item can appear in multiple pages

Expected Behavior
The order of the list should be stable in all pages.

Actual Behavior / Steps to Reproduce

1. Mark many movies with the same ratings. It will be easier to repro if the number is 3 or 4 times of the item number per page.
2. Go to the marked movie list, and sort by rating.
3. Randomly check the pages, it's easy to find the same movie in more than one page.

Possible Fix
When sorting by rating, add the second sorting key. Mark date is good enough.
