bugfix: filter flows on folder to ensure is displaying only for the logged user (#2897)

* 🐛 (generalBugs-shard-5.spec.ts): fix test to wait for elements to be interactable before performing actions to prevent flakiness

* 🐛 (folders.py): fix issue where all flows were being returned instead of only flows from the current user in the specified folder
