Fix bug in debug node due to msg.hasOwnProperty construct

Browse Source 
`msg.hasOwnProperty("status")` might make the debug node crash/produce an error if the payload was created with `Object.create(null)`.
This is the case e.g. for `ini` (to parse INI files), an official NPM node:
4f289946b3/lib/ini.js (L63)

My Node-RED node `node-red-contrib-parser-ini`, which is using that library, was hit by this bug and I had to ship a workaround
fe6b1eb4b1/parser-ini.js (L14)

The `msg.hasOwnProperty("xxx")` construct should not be used since ECMAScript 5.1.

ESLint advises in the same direction https://eslint.org/docs/rules/no-prototype-builtins

This patch was produced using the following regex:
Search: `\b([\w.]+).hasOwnProperty\(`
Replace: `Object.prototype.hasOwnProperty.call($1, `

This could be applied more gobally if desired.
