Fixed bug that redirects to just deleted entity

While deleting an entity from it's 'view' page, controller tries to redirect the user to the referer route, resulting in a not found exception as that entity was deleted.

This PR corrects the issue but I have hardcoded the routes. In case there is a better approach, let me know and I will change my PR.

I also corrected a small typo introduced in a previous PR: `admin_valuet_list`
