Cockpit: Nested Collection Links

[andrewl913]

Ran into an issue with the UI entry link menu when trying to port in a collection with a collection link that has a collection link , the relationship I have is parentCollection -> collectionLinkField -> collectionWithCollectionLink, the display shows as type [Object object]

the link selector pops up with this

These were made with the API, the one circled was made in the UI

Was also able to reproduce strictly in the UI to make sure it wasn't my logic.
Steps to reproduce

1. Create an a new collection named TestOne with a text field
2. Create another collection named TestTwo with collection link field to the TestOne's text field.
3. Create another collection named TestThree with collection link field to the TestTwo's text field.
4. Create entries in the first two collections and observe the that TestOne Text field is not being represented as JSON in TestThree's collection link selector

looks like this is a potential solution https://github.com/agentejo/cockpit/pull/517/commits
