Winston handles .error(message, err) okay, but not .error(err) by itself. For reability we also
want to make sure the provided message ends with a space so that the concatenated message from the
error is separate.

Due to a winston regression introduced in 3.x, we cannot pass other meta information after the error
without passing error.message and error.stack explicitly. This means we may lose additional error
properties. We cannot destructure the error either (non-iterable properties).

A better fix would be to write a custom log formatter that is error-aware. There are a few examples
on GitHub, but none that looked straightforward. We don't want to break JSON logging and parsing.
