Fix adding excluded users to the private room sharing tables when joining a room (#11143)
* We only need to fetch users in private rooms

* Filter out `user_id` at the top

* Discard excluded users in the top loop

We weren't doing this in the "First, if they're our user" branch so this
is a bugfix.

* The caller must check that `user_id` is included

This is in the docstring. There are two call sites:
- one in `_handle_room_publicity_change`, which explicitly checks before calling;
- and another in `_handle_room_membership_event`, which returns early if
  the user is excluded.

So this change is safe.

* Test joining a private room with an excluded user

* Tweak an existing test

* Changelog

* test docstring

* lint

This isn't about preventing a leak (the room is now public, so the nickname

I made this a Synapse test case rather than a Complement one because
I think this is (strictly speaking) an implementation choice. Synapse
has chosen to only ever use the public profile when responding to a user
directory search. There's no privacy leak here, because making the room
public discloses the per-room name.
The spec doesn't mandate anything about _how_ a user
should appear in a /user_directory/search result. Hypothetical example:
suppose Bob searches for Alice. When representing Alice in a search
result, it's reasonable to use any of Alice's nicknames that Bob is
aware of. Heck, maybe we even want to use lots of them in a combined
displayname like `Alice (aka "ali", "ally", "41iC3")`.
