Update test result after crrev.com/914233002

Blink's CL changes approach of colspan's calculating.
Calculation is based on effective columns's conversion.
Malformed colspan such as <table><tr><td colspan="10"></td><th></th></tr></table>
now is calculated as {0, 1} not {0, 10}
Update also a test case so that we could check valid colspans.
