clarify browser test names in test-index

Browser tests names are now something like 'cajajs-invocation-min-es53',
which is the name you'd use to run one test with -Dtest.filter.method,
but these names are not anywhere literally in the source any more,
and it's not obvious how to construct a valid name.

The test names are visible in the ant test report summary, but
test-index.html annoyingly does not show these test names.
It's possible to construct a valid test name from the info on
test-index.html, but the method for doing that is not obvious.

This change makes it obvious. test-index.html used to look like:

    cajajs
        invocation
            es53 es5 nomin
            es53 es5 min
            es53[min nomin] es5[min nomin] version-skew-js-files

It now looks like:

    cajajs-
        invocation-
            nomin- {es53 es5}
            min- {es53 es5}
        version-skew-js-files- {es53- {min nomin} es5- {min nomin}}

Add .comment to the selector on line 42 below instead of duplicating this value.
