No need Node.cloneNode() in Drupal.url.toAbsolute()

When this issue was created, the commit id 8c33fb4f was already committed but the commit id ce26a90e was not committed for the feature branch.
I rebased the feature branch and all tests ware passed.

Not sure why the GitHub link is removed, maybe that should be included in the summary too

Added the reason why jQuery UI URL is removed to issue summary.
Please review.

Believe this should be fine
