Expected Results

When going to Product Link screen the admin should be able to select or type in the "Destination URL" field the url used after the site rename and apply successfully link fixing.

Actual Results

Admin cannot select the new url in "Destination URL" field because it is a drop down list that only allows accepted values and the new url will not appear in the list. As a consequence, link fixing cannot be applied.
