Fix striking out the Ship It text when revoking.
Review Request #1163 — Created April 18, 2018 and updated — Latest diff uploaded
When revoking Ship It, the text is supposed to be updated to show a strike-through effect. This broke at some point when the template for the review entry was changed to better group some parts of a comment thread, preventing the element from being updated. This change fixes the unit tests to reflect the current structure, and fixes the query to look up the right elements. Testing Done: Revoked a Ship It. Saw that the text updated. Unit tests all pass.
