Currently, if there are global namespaces configured and no per-object
namesapces, while there is both a global and a per-object labelSelector,
we will:
1. Default the namespaces labelSelector from `DefaultLabelSelector`
2. Copy the namespaces including config into `byObject.Namespaces`

And thus end up with the global labelSelector overriding the per-object
one, this change fixes that by swapping step 1 and 2.
