 Removed containers are not always waiting

fixes #54499 
The issue was that a container that is removed (during pod deletion, for example), is assumed to be in a "waiting" state.
Instead, we should use the previous container state.
Fetching the most recent status is required to ensure that we accurately reflect the previous state.  The status attached to a pod object is often stale.

I verified this by looking through the kubelet logs during a deletion, and verifying that the status updates do not transition from terminated -> pending.

```release-note
Fix an issue where pods were briefly transitioned to a "Pending" state during the deletion process.
