When a row is reused, the new result has showFeedbackMenu, and the old result didn't, the row won't show the Feedback menu button. We need to create new row content in that case.

This hasn't been a problem before because the Feedback button was only shown in best matches, which practically are never reused. Pocket non-best-match rows will show the button, which is how I noticed this.

Depends on D182537

STR for QA:

1. Set browser.urlbar.pocket.featureGate = true to enable Pocket suggestions
2. Type "breakfast" and verify a low confidence (non-top-pick) Pocket suggestion appears
3. Verify the Feedback button appears in the suggestion
4. Modify your search string several times so the suggestion goes away and reappears (e.g., backspace over the last few characters, type a few extra characters, etc.) and verify the Feedback button always appears in the suggestion
