console.group() emits duplicate CDP messages

* **Version**: v12.11.1 * **Platform**: Darwin 10.14 ### What steps will reproduce the bug? With a debugger attached, invoke: ``` console.group('group name', { foo: true }); ``` ### How often does it reproduce? Is there a required condition? Every time ### What is the expected behavior?

Running that line of code in Node.js, I get two messages--the correct `startGroup` type, and then an additional log message whose stack says it comes from the `group` method in `internal/console/constructor.js` ```json {"method":"Runtime.consoleAPICalled","params":{"type":"startGroup","args":[{"type":"string","value":"group name"},{"type":"object","className":"Object","description":"Object","objectId":"{\"injectedScriptId\":1,\"id\":1}","preview":{"type":"object","description":"Object","overflow":false,"properties":[{"name":"foo","type":"boolean","value":"true"}]}}],"executionContextId":1,"timestamp":1582746620974.181,"stackTrace":{"callFrames":[{"functionName":"","scriptId":"97","url":"file:///Users/copeet/Github/vscode-pwa/demos/node/main.js","lineNumber":1,"columnNumber":8},{"functionName":"Module._compile","scriptId":"43","url":"internal/modules/cjs/loader.js","lineNumber":944,"columnNumber":29},{"functionName":"Module._extensions..js","scriptId":"43","url":"internal/modules/cjs/loader.js","lineNumber":961,"columnNumber":9},{"functionName":"Module.load","scriptId":"43","url":"internal/modules/cjs/loader.js","lineNumber":797,"columnNumber":31},{"functionName":"Module._load","scriptId":"43","url":"internal/modules/cjs/loader.js","lineNumber":710,"columnNumber":11},{"functionName":"Module.runMain","scriptId":"43","url":"internal/modules/cjs/loader.js","lineNumber":1013,"columnNumber":9},{"funct…
