Only display Talks for the current conference in the talk views.

At https://ep2019.europython.eu/talks/python-3-ten-years-later/ the slides link points to https://ep2019.europython.eu/media/conference/slides/python-3-ten-years-later.pdf which is broken, gives a 404 not found error!?

Thanks for catching it - the talk is actually from last year's conference, you can view the details and the slides under https://ep2018.europython.eu/conference/talks/python-3-ten-years-later. Where did you find the link to the talk, @cdeil ? I'll remove it from there and update the ticket description - we should only return talk information for the current conference.

@umgelurgel - Found the page via Google. Thanks for taking care of this!
