Fix: handle HTML entities correctly in usernames

In the "previous posts" links generated by the extension, if the
username contained HTML entities, the entities would appear as is and
wouldn't be rendered to the correct character.

An explanation about why this regression occured can be read at
issue 17.

Fixes: #17
