`now domain` doesn't handle authentication errors about vercel

[OlliV]

I don't think there is any command handling it properly.
For example:

$ now dns ls -t re
> Error! Unexpected error. Please try later. (Cannot read property 'filter' of undefined)
$ now certs ls -t a
> Error! Unexpected error. Please try later. (Cannot read property 'length' of undefined)

Let's make this work properly!

Closing, since this is what is shown today:

$ now domain ls -t bad
> Error! The specified token is not valid

$ now dns ls -t re
> Error! The specified token is not valid

$ now certs ls -t a
> Error! The specified token is not valid
