issue with test testsuite/bugs/4469.css

There is an issue with the autotest or with css-validator servlet.

They are failing with testsuite/bugs/4469.css

<style type="text/css">

body
{
        font-family: Verdana, Geneva, Arial, Helvetica, sans-serif;
}

</style>

The expected result is 2 errors.
However the testsuite doesn't query the servlet properly.
Actually, so that the servlet returns 2 errors, one has to set the "type" to CSS. If the "type" value is automatic, it will tell that the code is valid.

If it is tested through the jar, then it really reports 2 errors.

Start with testsuite/bugs/4469.css and the autotest path that queries the CSS-validator servlet. Compare the servlet request with the jar behavior, especially the automatic versus CSS type value. Done means the test reports the expected two errors through the servlet as well as through the jar.
