Fix erroneous HTTPS links in click-noreferrer-links.html test file.

Fix erroneous HTTPS links in click-noreferrer-links.html test file.

After a recent test server refactoring (https://codereview.chromium.org/163753003), a few links in this file were left with an incorrect scheme (HTTPS instead of HTTP).  This was affecting tests that used these links, such as DontSwapProcessWithOnlyTargetBlank which was breaking with --site-per-process and passing "by accident" without --site-per-process (since the error page ended up in an expected SiteInstance).

This bug wasn't caught due to many tests not checking for page load success (issue 425335).  This is being addressed in a separate CL: https://codereview.chromium.org/681113002/

BUG=425335,417518
TEST=*.DontSwapProcessWithOnlyTargetBlank passes with --site-per-process
