Error message for expired token could be clearer

[tbm]

I upgraded from 3.4.0 to 4.2.0 recently. I can't test 3.4.0 easily now because of the config changes, but I think the error message for expired tokens was clearer there.

Now it shows the "Usage" text (but I called the program correctly so why are you showing this?) and shows the errors twice.

I think it should show the error and then tell me to run gphotos-uploader-cli auth. Thanks
