Update "You are not logged in!" Message

[TerrySmithDC]

Suggestion

More than once when my login expires I spend a few minutes to figure out which auth has expired. It would be handy to specify it's the manifold-cli that isn't logged in.

Example

> manifold run node server

You are not logged in!
npm ERR! code ELIFECYCLE
npm ERR! errno 255
npm ERR! [email protected] start: `manifold run node server`
npm ERR! Exit status 255
npm ERR!
npm ERR! Failed at the [email protected] start script.
npm ERR! This is probably not a problem with npm. There is likely additional logging output above.

Suggested

> manifold run node server
