    build: Run tests one at a time when collecting coverage
    
    Unfortunately the JS coverage is all written to the same file, so it
    needs to be written sequentially. Running the tests in parallel which
    meson did by default was creating garbage LCOV data.
    
    Unreviewed, pushing to fix coverage build.
