[Findit] Fix paging issue with ranked flakes page.

Before we only rank flakes by false_rejection_count_last_week, but if there are entries with the same false_rejection_count_last_week, the paging may act weirdly and if users click next then previous they may not get the same page. Add last_occurred_time as the secondary field for ordering to fix the issue.

[Findit] Flake Detection UI: add normalized_step_name and test_label_name to order_properties

The paging for ranked flakes dashboard still had issues because the last_occurred_time of flakes are still likely to be the same.

Add normalized_step_name and test_label_name to order_properties as well to ensure the entities can be ordered in a unique way.
