Debug output is unable to print command names

[aieri]

Describe the bug
When invoking debug logging for command checks I would expect the output to include the check name and resemble what was shown in #816 (comment).
In place of the check name I see %!s(<nil>) instead.

How To Reproduce

Given a goss.yaml as follows:

command:
  foo:
    exec: echo "this is a test"
    exit-status: 0

Expected Behavior

$ goss -l debug v
2025-01-24T20:54:31Z [DEBUG] Setting log level to DEBUG
2025-01-24T20:54:31Z [DEBUG][Command][foo][stdout]  this is a test
2025-01-24T20:54:31Z [DEBUG][Command][foo][stdout]  
.
