This PR proposes supporting empty strings as messages to support the following use case:

const MyError = createError("MY_CODE", "", 400)
// before -> throws error
// after -> works

throw new MyError() // message = ""
throw new MyError("broken") // message = "broken"

This supports the use case where the user doesn't desire any prefix or suffix to the message; they want the message to match the argument passed to the error.

The trim() I admit is a little problematic, but without it, the above example looks like:

throw new MyError("broken") // message = " broken" (note the space)
