  - Remove javascript from sonar

    Per Catherine, Dublin will not require javascript for sonar
    coverage statistics. We'll add this back in for El Alto if
    we determine this repo still needs development.

    If LF turns off javascript in the Sonar application then I'll
    change this back. But I need to determine if policy/engine has
    55% coverage for tomorrow M2.
