[Bug] `dbt debug` duplication of profiles field in output: sslmode, region

[Florian Eiden]

When I run dbt debug on a Redshift profile in 1.6.7 I get:

23:15:36  Connection:
23:15:36    host: ....redshift.amazonaws.com
23:15:36    user: ...
23:15:36    port: 5439

23:15:36    schema: ...
23:15:36    sslmode: prefer
23:15:36    region: None
23:15:36    sslmode: prefer
23:15:36    region: None
23:15:36    iam_profile: None

23:15:37    Connection test: [OK connection ok]

With sslmode and region both duplicated. It does not bring joy, but it doesn' break anything.
