Clean up folder API requests

[dixonnataliej]

When navigating to a folder view, users must press the back button 3 times to return to the previous page. This is caused by 3 simultaneous API requests being made when opening a folder:

GET /folders/{slug} - Folder details
GET /folders/folder_slug_list - All folders list
GET /folders/{slug}/get_name - Just folder name

Review folder api requests in general and try to optimize the way we're sending and receiving data, look into what the front end actually uses.
