Add testcase for internal used Comparator in ClientCookieEncoder (#9897)

Motivation:

https://github.com/netty/netty/pull/9883 added a bug-fix for the Comparator in ClientCookieEncoder but did not add a testcase.

Modifications:

- Add testcase
- Simplify code

Result:

Include a test to ensure we not regress.
