Fix foaf profile

[SvenLieber]

There is some issue with my foaf profile preventing rendering on https://knows.idlab.ugent.be/team/

The turtle file was invalid (fixed in 69c6396)

But there is also an issue with the CORS headers, i.e.

• This works (url https://sven-lieber.org/profile/profile.ttl: http://query.linkeddatafragments.org/#datasources=https%3A%2F%2Fsven-lieber.org%2Fprofile%2Fprofile.ttl&query=select%20*%0Awhere%20%7B%0A%20%20%3Fs%20%3Fp%20%3Fo%20.%0A%7D
• This does not work (url https://sven-lieber.org/profile#me): http://query.linkeddatafragments.org/#datasources=https%3A%2F%2Fsven-lieber.org%2Fprofile%23me&query=select%20*%0Awhere%20%7B%0A%20%20%3Fs%20%3Fp%20%3Fo%20.%0A%7D

Even though curl -v -L -H "Accept: text/turtle" https://sven-lieber.org/profile reports that the CORS header is set correctly:
