refactor(tests): Remove TestEndpoint::addr

[flub]

Description

The RoutingTable is in charge of which addresses a TestEndpoint
has. So now all decisions are made there remove the addr field and
clean up any remaining usages. This should avoid confusion in the
future.

Notes & open questions

Maybe I'm finally done with cleaning up existing test infra. I'm
medium enthusiastic about this whole thing. I think it's an
improvement but there's definitely some things that look more complex
now. And some of the tests still do just plain weird stuff. Like when
opening a 2nd path we should now probably have a router that has a 2nd
path. But it was originally written without any router so cheated by
disconnecting the first path and relying on not reaching the
keep-alive interval or idle-timeout of the first path. So those are
still further improvements. But I need to work towards writing my
test, so I'll stop here.

Change checklist

• Self-review.
• Tests if relevant.
