Description

Ampersands were being encoded in resource topic labels on the single resource view, on resource cards, and on term lists. Links to publishers were being displayed on resource cards.

Steps to test

1. Add a topic with an ampersand in the title.
2. Apply it to a resource.
3. Examine the resource card and single resource view.
4. Examine the term list in which the topic appears.

Expected behavior: The ampersand should be displayed normally (&), not encoded (&). No publisher links appear on resource cards.
