Links containing HTML escaped characters, such as the ampersand `&` escaped `&` were not shortened correctly: Their redirecting URL contained the escaped value (e.g. `&`) instead of the actual character, leading to the wrong redirected URL. e.g. creating a mass-mailing with a link contains as query string ?test1=1&test2=2 were shortened with as redirect link ?test1=1&test2=2 opw-708272
