fixed error in second assertion (line 35)

I'm pretty sure that given line 15:
    `<input id="valid" type="date" value="2011-11-01" min="2011-01-01" max="2011-12-31" />`
line 35 should be
    `assert_equals(document.getElementById("valid").value, "2011-11-01");`
not
    `assert_equals(document.getElementById("valid").value, "2011-01-01");`
