Remove clientapi producers which aren't actually producers (#1111)

* Remove clientapi producers which aren't actually producers

They are actually just convenience wrappers around the internal APIs
for roomserver/eduserver. Move their logic to their respective `api`
packages and call them directly.

* Remove TODO

* unbreak ygg
