Issue Type: Bug

Run debug with the following debugger setup:

{
      "name": "Debug Jest Tests",
      "type": "node",
      "request": "launch",
      "port": 9229,
      "runtimeArgs": [
        "--inspect-brk",
        "${workspaceRoot}/node_modules/.bin/jest",
        "--watch",
        "--bail",
        "--runInBand"
      ],
      "console": "integratedTerminal",
      "internalConsoleOptions": "neverOpen",
      "runtimeExecutable": "${env:HOME}/.nvm/versions/node/v8.11.1/bin/node",
      "skipFiles": [
        "lodash.js",
        "zone.js",
        "tslib.js",
        "angular",
        "browser-sync*",
        "pdf-make*"
      ]
    },

Getting this error in the CALL STACK pane and no breakpoints are hit.
