Fix running reconcileDelete on new instance

dda3b1e
refactored code and introduce the situation that on the just created
new instance the reconcileDelete method runs which we can see from
the operator log:

~~~
2024-10-08T21:45:28Z    INFO    ceilometer-resource     default {"name": "ceilometer"}
2024-10-08T21:45:28Z    INFO    ceilometer-resource     validate create {"name": "ceilometer"}
2024-10-08T21:45:28Z    INFO    Controllers.Ceilometer  Reconciling Service delete      {"controller": "ceilometer", "controllerGroup": "telemetry.openstack.org", "controllerKind": "Ceilometer", "Ceilometer": {"name":"ceilometer","namespace":"openstack-kuttl-tests"}, "namespace": "openstack-kuttl-tests", "name": "ceilometer", "reconcileID": "c205bb0b-1c34-4350-969a-06c0925e0cdf"}
~~~

This change moves reconcileDelete in its own condition.
