node tests: Use EXEMPT_FILES for line coverage.
We now have 100% line coverage on 71 JS files. This is thanks to about 150 people who have contributed code to frontend/node_tests. And then 126 files are still short of 100% line coverage. We now enforce line coverage with a set called EXEMPT_FILES, which are the files for which we do NOT expect to have 100% coverage. Using an exemption list makes it so that adding a new JS file to the project without 100% line coverage will cause the build to fail. This will encourage folks to be intentional about their lack of test coverage.
