🐛 Bug Report

Jest fails to run on React Native 0.59.5

To Reproduce

1. update react native 0.59.3 -> 0.59.5
2. have jest config:

  "jest": {
    "preset": "react-native",
    "transform": {
      "^.+\\.(jsx?)$": "<rootDir>/node_modules/react-native/jest/preprocessor.js",
      "^.+\\.tsx?$": "ts-jest"
    },
    "transformIgnorePatterns": [
      "node_modules/(?!react-native)/"
    ],
    "globals": {
      "window": {},
      "ts-jest": {
        "tsConfig": "./tsconfig.jest.json"
      }
    }
  },

1. run jest ./node_modules/.bin/jest
2. get the following error

$ ./node_modules/.bin/jest
No tests found
In /Users/ethanneff/Dropbox/active/dev/react-native/example
  712 files checked.
  testMatch:  - 712 matches
  testPathIgnorePatterns: /node_modules/ - 190 matches
  testRegex: (/__tests__/.*|(\.|/)(test|spec))\.(jsx?|tsx?)$ - 2 matches
