Fix #134 0.76.0: SNS -> publish to subscribed SQS queue, "Records" as…

…sumption leads to lost message, empty array. #134

There is no need to check `    if (sub["Attributes"]["RawMessageDelivery"] === "true") ` inside `publishSqs`, this `RawMessageDelivery` check-process is already handled by `publish`.
The `event` object is what should be sent directly to an sqs endpoint.

This also works with serverless-offline-sqs plugin.
