Promote Integration operator warning

[squakez]

It happens when promoting any integration from a namespace to another:

camel-k-operator-9b9f56d75-c827n camel-k-operator {"level":"info","ts":"2024-05-23T14:23:59Z","logger":"camel-k","msg":"Cannot get information about the creator Integration &ObjectReference{Kind:Integration,Namespace:default,Name:test,UID:,APIVersion:camel.apache.org/v1,ResourceVersion:,FieldPath:,}: unable to get: default/test because of unknown namespace for the cache"}

It does not seem harmful, but it requires to be fixed.
