Prefer err.message when reporting errors from dockerode, then err.json and err.reason

Browse Source 
Errors from docker-modem that are passed from dockerode can have a "json" or "reason" property,
but that is generally less descriptive than the more standard "message", and can show up in the logs
as `[object Object]`. This commit changes it so that we log err.message if it is non-empty, and otherwise
look for json and reason.
