Fix an issue where bookmarking https: sites doesn't work.

Fix for issue 1863535.  We were storing https:// sites in
the database without https:, so it was stored as a non
secure site.  Then going back to that bookmark does not work.
Now, use the truncated url to compare, but store the original
url (with https at the beginning)
