switching openwhisk namespaces does not emit confirmation of switch

[starpit]

If you are working with multiple openwhisk namespaces, when you switch between them via auth list then select, there is confirmation emitted of the change.

I believe this used to emit something like "ok you're not using ...". I think a positive and explicit confirmation would be helpful. Note that when you swtich kui themes, say from light to dark, the visual confirmation is the theme change itself.

I think it's quite confusing to switch namespaces without telling the user it was actually successful.
