"contact on slack" stopped working

[glbert-does]

"contact on slack", on player pages, e.g. https://www.lichess4545.com/team4545/player/glbert/ stopped working. it will just open #general, not a dm.

currently we use the format https://lichess4545.slack.com/messages/[user_id]/ here:

heltour/heltour/tournament/templates/tournament/player_profile.html

Line 47 in 1d5fd89

<a href="https://lichess4545.slack.com/messages/{{ player.slack_user_id }}/">Message {{ player.lichess_username }}

as far as i can tell, instead using the format https://app.slack.com/client/[team_id]/[user_id] would work. edit: it doesn't work. instead, https://slack.com/app_redirect?team=[team_id]&channel=[user_id] sort of works, but maybe there is a better solution.

marked this as "good first issue" for now, because i assume that it is. but i might be wrong.
