Make language server id more explicit in unhandled message logs (#8131)

Kirill Bulatov created

Before:
```
[2024-02-21T18:55:55+02:00 INFO  language::language_registry] starting language server "eslint", path: "/Users/someonetoignore/Downloads/eslint-configs-demo", id: 2

}
```

After:
```

}
```

We have to pass a name there too, but the problem here is that the
unhandled message callback is created very early, along with the binary,
but the server name is received from the LSP initialize response, which
is a totally separate piece of code.
I plan to refactor that code next, but so far, improve the logs at least
slightly.
