Patrick East f1b9c7586b Ensure all errors are in JSON formatted CLI output
Previously if the errors passed into the presentation Output were not
structured w/ JSON tags for marshaling the error would be an empty
string.

This changes to wrap the errors with a struct in cases where they
would otherwise not be formatted. We do this by forcing every error
into a structure and translating known error types into it.

Fixes: #1724
