Add "Stop Tracking" link to entries in the Phrequent search view.

Summary: Depends on D7163.  This adds a "Stop Tracking" link to the right-hand side of ongoing entries in the Phrequent search view.  It allows users to stop tracking items without first navigating to the item itself.

Test Plan: Started tracking and item and then clicked the "Stop Tracking" link in Phrequent.
