client: use updatedClient to fix cache problem

[YangKeao]

Signed-off-by: YangKeao yangkeao@chunibyo.icu

What problem does this PR solve?

After #2509 , the cache in client breaks the twophase controller:

1. The controller updates the chaos into Running.
2. The controller reconciles the chaos, gets a cache and think it's waiting
3. Step into the finished state, merge the conflict, remove the finalizer and step out.

In this PR, I backported the UpdatedClient in release-2.0 to make the cache at least updated to the latest successfully Updated object.
