Fix bug in status manager TerminatePod
In TerminatePod, we previously pass pod.Status to updateStatusInternal. This is a bug, since it is the original status that we are given. Not only does it skip updates made to container statuses, but in some cases it reverted the pod's status to an earlier version, since it was being passed a stale status initially.
This was the case in #40239 and #41095. As shown in #40239, the pod's status is set to running after it is set to failed, occasionally causing very long delays in pod deletion since we have to wait for this to be corrected.
This PR fixes the bug, adds some helpful debugging statements, and adds a unit test for TerminatePod (which for some reason didnt exist before?).
