This fixes https://github.com/dart-lang/sdk/issues/55889 which is repeat of https://github.com/Dart-Code/Dart-Code/issues/3929 (but semantic tokens was not fixed with that CL). The issue was when the server was initialized with no roots (for example an empty workspace) and then a new file opened with requests being sent immediately before the roots were updated. The fix changes from directly calling `server.getResolvedUnit` to instead using `requireResolvedUnit` which handles this situation by waiting for any in-progress context changes and retries.
