Discovered an unhelpful error when running a CLI command without internet (I didn't know I didn't have internet!):```$ coder lsEncountered an error running "coder list", see "coder list --help" for more informationerror: <nil>```The source of this was that calling `Unwrap()` on `net.DNSError` can return nil, causing the whole error trace to get replaced by it. Instead, we'll just treat a nil `Unwrap()` return value as if there was nothing to unwrap.The result is:```$ coder lsEncountered an error running "coder list", see "coder list --help" for more informationerror: query workspaces: Get "https://dev.coder.com/api/v2/workspaces?q=owner%3Ame": dial tcp: lookup dev.coder.com: no such host```
