Subject: [PATCH] hovercard: Fix hover card domain label for about:blank tabs

Previously, the hover card domain label for about:blank tabs was not
handled explicitly, which could cause incorrect domain text to be
displayed. This patch adds an explicit check for about:blank URLs and
sets the domain label to url::kAboutBlankURL16 accordingly.
