Editing a Listener and changing the spec.host field creates a new service, but does not remove the old one

[granzoto]

Describe the bug
Create a listener using spec.host equals to backend-ha, then edits the listener and changes its value to backend.
Check that a new service named backend is created, but the old one, named backend-ha was not removed

How To Reproduce
Create two skupper sites
Create an accessgrant and an accesstoken, establish the connection
Deploy a workload ( backend ) in one site
Create the proper connector and listener for the service/workload

From the listener definition :
spec:
host: backend-ha

services Created:
NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S)
backend-ha ClusterIP X.X.X.X <none> 8080/TCP

Edit the listener and change the spec.host field.

This should start the creation of a new service, and also remove the old service

New host address in the listener definition :
spec:
host: backend

The new service is created as expected, but the old one remains untouched
NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S)
backend ClusterIP X.X.X.X <none> 8080/TCP
backend-ha ClusterIP Y.Y.Y.Y <none> 8080/TCP

Expected behavior
The new service should be created and the old one should be removed
