Use correct element for Form Not Secure warning

Use correct element for Form Not Secure warning

Web forms may not contain a username element, therefore it is not safe
to assume that such an element exists when calling ShowNotSecureWarning.
Instead, use the actual element found by the autofill logic.

PTAL? This is a tiny fix to a corner case for Form-Not-Secure UI; that feature
will be enabled via Finch imminently.

Thanks!
