importer: Allow user to import some missing URLS.

More specifically, we were not allowing the user to import chrome://chrome
and chrome://about. We add the necessary checks and now the user can import
those urls too.

BUG=283715
TEST=launch chrome, go to bookmarks manager, select "Import Bookmarks from HTML
file", choose an html file that contains either chrome://chrome or chrome://about
or both, verify that now we can import those.
