[FIX] link_tracker: get redirected page title instead of URL

In 2e3075693b06d71222b446bd8a805dacb639d0e4 we used a head request to
determine type of page before trying to get a title out of it.

But requests.head does not allow redirect by default:

https://docs.python-requests.org/en/v2.9.1/user/quickstart/#redirection-and-history

so if an URL was a redirect, we would not longer get the page title.
