Distinguish between NotAuthenticated errors in @feathersjs/authentication-client

[sebastien-prudhomme]

Hi,

When using OAuth there are two kind of NotAuthenticated errors that are throwed by the @feathersjs/authentication-client module:

• one with the message "No accessToken found in storage" that is not really an error but a failed try to authenticate with a previous token
• one that is throwed because there is an error field found in the redirect (http://www.example.com/#error=myerrormessage)

It will be great to distinguish between these two errors so that we can give user some feedback when there is a problem in Oauth workflow but not when there is no token in its local storage.
