ValueError: Should never happen

[devl00p]

Describe the bug
ValueError: Should never happen is raised on certificate_info scan command

Here is the output I got:

 * Error when running --certinfo:
       You can open an issue at https://github.com/nabla-c0d3/sslyze/issues with the following information:

To Reproduce
Steps to reproduce the behavior:

1. Install sslyze==4.1.0
2. Run the following command 'sslyze vpn.technofreudian.com'
3. See error

Expected behavior

I hope it helps. Keep up the good job, great tool :)
