Use more reliable element to grab Autofill info

For each input element, we grab the autofill information from
the html element and log it. FormCache writes to 2 elements, and
sometimes title is used on the page, so switching to use
"autofill-information" instead

Also, making the lack of this element a simple log line instead
of a failure as it doesn't affect validation or execution of test.
