Use requestFocusNodeHref to get the link for an image.

Bug:3198707

We were attempting to use WebView.HitTestResult.getExtra()
to find the href.  For normal links, this is okay.  For
image links, this is the URL of the image itself.  Instead,
use requestFocusNodeHref, which will get the URL of the link.
