Access of any core property (as `hasOwnProperty`) or not existing property returns a method as generated by [`createCustomMethodHandler`](https://github.com/serverless/template/blob/fdc1924136d13e06200917cced8227de53b6d2b3/utils.js#L344)  This may turn nasty, when we pass such object to any generic util, or if any developer decides to handle it in some outer module. It's caused by optimistic Proxy setup: https://github.com/serverless/template/blob/fdc1924136d13e06200917cced8227de53b6d2b3/serverless.js#L31
