It seems there are a number of links that still point to twl-test instead of wikipedialibrary. One example is in the emails sent to users - <noreply@twl-test.wmflabs.org> is used. This should be updated to noreply@wikipedialibrary.wmflabs.org.
Another example is on a partner page in /admin/partners, the 'View on site' button links back to twl-test instead of wikipedialibrary.
We should go through the code and make sure that there are no remaining links to twl-test.
