Fix: stop using redirects in collections

[nielslyngsoe]

This is not a certain fix, but we generally seen redirects as bad.
Its because we sometimes have a case where the browser loads the Media section before Content, and a redirect of the Media Section changes the URl so they user now stays on Media, despite the user did not want to navigate to the media section.

It only happens occasionally so this is more of a try, by doing the thing we have done elsewhere to fix this issue — which is stop using redirects. :-D

Great! This also resolves another issue where navigating to a folder (Ex. Document Types Root) would not highlight the sidebar menu item as active due to the redirects. 👍
