[FIX] link_tracker: convert link with ampersand

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
