Can't add Multiple Collection Descriptions

[mark-dce]

BUG Steps to repeat

• Create a new user or class collection
• Enter data for the title & description
• Click on the + icon to add an additional description EXPECTED RESULT: the application displays a new field for an additional description ACTUAL RESULT: the application loads the homepage

NOTE: The same behavior occurs if you try to add an additional description to an existing collection.

COROLLARY If you add additional descriptions via the console, they will appear on the edit screen, but trying to remove them results in the system returning the show view without modifying the descriptions.

ACCEPTANCE

• [x] PREFERRED Multiple collection descriptions behave like multiple image descriptions in MIRA (i.e. the UI allows me to add and delete more than one description)
• [ ] CHEAP AND UNFULFILLING Remove the + icon form the form so the user can't attempt to enter multiple collection descriptions.

This works differently for me. If I'm on the collections#show page and click edit, the + button sends me back to the previous page (collections#show). If I paste the url into the location bar, the + buttons works as expected. This might be a turbolinks thing. It'll probably be easy to fix, but could be hard to figure out.
