Bug 35374: Remove ES6 template literals to fix translation strings

The .po files contains the whole block after this line. I don't really
understand what's happening but this change fixes the problem.

Test plan:
1. Run the following command before and after the patch and compare the
diff
% gulp po:update --lang de-DE --task messages-js
2. Confirm that the list on this vue is correctly populated
