🐛 test/e2e/framework: Don't try to pull logs from a non-ready POD

[jmprusi]

Summary

Fixes some flaky tests due to the syncer-dns pod not being in "running" state (synctarget heartbeat is sent by the syncer pod, and doesn't take into account the syncer-dns POD state.)

This is causing some e2e-shared tests to fail, due to the collecting of logs failing as the syncer-dns pod is not ready.

related to: #2284

If the pod has stopped, etc, we can get the previous logs from it - can we add that as well?
