Cleanup unused caps

They don't add anything in the UI, and generate useless traffic.

Account tracking is not used:
- account-notify
- account-tag
- extended-join

We don't really care about users, hosts, nor real names:
- extended-join
- userhost-in-names

away-notify and invite-notify are also not used, but will be in the near
future.
