Bug 12849 - fix URLs in sent lists

This brings back the http(s) to the URLs in sent lists.

Test plan:
* make a list
* send it to yourself
* see that the URLs aren't clickable
* apply the patch
* repeat, except now the URLs are better

By removing this bit of code, the code in Auth.pm is used
instead. The code there is not perfect, but the solution
works and both list and cart use the same code.

Passes tests and QA script.
