some: remove some referral links

* Diaspora invite, I think the pod was overpopulated previously and it's
  not good that everyone is on the same server.
* Foodora, their mobile app is horrible and I cannot figure out where to
  get the referral code or text and if I was ordering something, I would
  be more likely to do it with Wolt or Resq.Club.
* LastPass, I have moved to Bitwarden ages ago.
* Uber, I have never rided it and there are weird things in their data
  collection etc. so I don't want to advertise them.

Closes #119
