Flaky: TestGameServerCreationAfterDeletingOneExtensionsPod

Thanks to extended logging I noticed that in some cases a `Failed`
status Pod could just hang around for a while, even though there were
the correct number of Pods up and running -- which would break this
test.

This changes things such that we only care about counting running Pods,
and ignoring everything else.

Closes #3599
