verbose command output and logs

Description of problem:

When checking the status and/or registering using the insights-client a fatal error occurs and a traceback is printed. The registration still works.


Version-Release number of selected component (if applicable):

3.0.5-4.el8


How reproducible:

I've reproduced it on three different VMs, but all are based on the same image/template. 


Steps to Reproduce:

1. dnf install insights-client
2. insights-client --register --verbose
3. insights-client --status --verbose


Actual results:

The commands works as expected, but there's a traceback printed even though I've not added the "--verbose" flag.

# insights-client --status
Fatal error

Insights API confirms registration.


Expected results:

User friendly output and not a traceback, e.g. "The Ingihts API conforms registration but an error occured."
