"""
This file has API and webface tests for when an entity references another
entity which is deleted/redirected/wip. For example, a release points to a
container (via container_id) which is deleted.

Current set of such references:

    => release -> collection
    => release -> creator
    => release -> file
    => file -> release
    => release -> work
    => work -> release
