Create DAO with duplicate name

[n13]

Describe the bug
Creating a DAO with the same name as an existing DAO causes problems because they share the same URL

To Reproduce
Steps to reproduce the behavior:

1. Create DAO page
2. Create a DAO with the same name as an existing DAO (not case sensitive)
3. On the main page, click on the new DAO to see the detail page

Current behavior
Detail page shows the old DAO with the same name

Expected behavior
Detail page shows the new DAO with the same name

Fix Suggestions
We may need to enforce a unique title - I think currently though this functionality is mainly used by DAOs who have to start over.
We definitely need to enforce a unique short URL, both when creating a new DAO, and when changing the short URL.

Additional context
We need to either prevent people from creating a DAO with the same title as an existing DAO, or else, create a new short URL to make sure short URLs are unique.
