Dry run tries to use empty namespace

[squakez]

The CM is available in the namespace (default). However, the CLI tries to use "" namespace (empty).

$ kamel run my-route.yaml --config configmap:my-cm -t container.limit-cpu=0.1 -t container.limit-memory=256Mi -o yaml > base/my-it.yaml
Warn: my-cm Configmap not found in  namespace, make sure to provide it before the Integration can run
