Previously, we weren't fully clearing the state associated with projects and worktrees when losing connection. This caused us to not see guest avatars disappear and not be able to re-share upon reconnect.

Also, increase the receive timeout to 30 seconds. We'll still respond immediately
to explicit disconnection, but when there are temporary network blips that
delay pings, we think we should err on the side of keeping the connection
alive. This is in response to a false positive 'host disconnected' state
that we observed when pairing today, while the host (Keith) still clearly
had a working internet connection, because we were screen sharing.

* Make advance_clock more realistic by waking timers in order,
instead of all at once.
* Don't advance the clock when simulating random delays.

When a network connection is lost without being explicitly closed by the
other end, writes to that connection will error, but reads will just wait
indefinitely.
This allows the tests to exercise our heartbeat logic.
This allows us to drop the context *after* we ran all futures to
completion and that's crucial otherwise we'll never drop entities
and/or flush effects.
However, the randomized integration test is still failing:
```
ITERATIONS=100000 SEED=3027 OPERATIONS=200 cargo test --release test_random --package=zed-server -- --nocapture
```

Instead, create an empty worktree on guests when a worktree is first *registered*, then update it via an initial UpdateWorktree message.
This prevents the host from referencing a worktree in definition RPC responses that hasn't yet been observed by the guest. We could have waited until the entire worktree was shared, but this could take a long time, so instead we create an empty one on guests and proceed from there.
We still have randomized test failures as of this commit:

Also, add completion requests to the randomized collaboration integration test,
to demonstrate that this is valid.

Some types of messages, which entail state updates on the host, should be
processed in the order that they were sent. Other types of messages should
not block the processing of other messages.

* On the server, spawn a separate task for each incoming message
* In the peer, eliminate the barrier that was used to enforce ordering
of responses with respect to other incoming messages
